I have tried everything to get my Phenom II 940 down in temperatures. Right now it's at 3.5ghz @ stock voltage, bumping it down to stock speed does nothing for the temperature. Depending on ambient if I do a Everest stress quest it will move up to 59c, and at times 60c. I am now using the Arctic Cooling Xtreme Freezer, which seems to be fantastic, best mounting system I've seen for AM2+ as well, but the temperatures are hardly different.

At first I used the orignal Arctic Cooling compound that was pre-applied, MX-2 I think, since with the new cooler I was around 43c idle, 55-58c load. Now I applied Arctic Silver 5, and idle around 45c again, and if loaded, will more than likely go past safe temperature, and I highly doubt after break-in of AS-5 it will be much safer. I'm reading about people with the STOCK heatsinks getting 33c idle, how is this possible? I used the grain of rice method as AS-5 says to use on AMD-Quad, and there is just no way it's going below 45c idle. Do I have a bad processor? Temps were taken with Everest, and Speedfan, bios report the same.

Specs are
Asus M3A79-T Deluxe (flashed with most recent bios)
Phenom II 940 @ 3.4ghz
4GB OCZ 1066 Reaper Ram
Vista Ultimate 32-Bit
Corsair 750w PSU
Dual Radeon 4870 1GB in Crossfire

I'll include a pic to verify proper airflow and organization for flow, ect.

Thanks in advance for your help, as I'm out of ideas, unless the bios are magically sending out bad temperature reports to Everest and the other programs...

60c underload is fine.
Get worried if it starts hitting 80.

I thought the Phenom II 940 had a maximum safe core temp of 62c...?
Edit* Tried the stock heatsink, around the same temperatures...at this point I find it unbelivable that people are running their Phenom IIs anywhere near 33c idle...

Quick question, I've been researching and found that apparently AMD only put in one sensor in the Phenom lineup for temps, however, I have multiple. I have Core 0, Core 1, Core 2, Core 3, all of those are the EXACT same temp as eachother (rather high and spikey, and easily go from 45c to 60c within seconds of a Everest test) however, temperature under everest just call "CPU" stays at a solid 43c, and dosen't seem to flutuate anything like the cores (temperature rising 15c in a second is insane, and I can't believe it's accurate).

I'm pretty sure I'm getting false core readings, but I just don't know whats right and whats wrong, whats safe and whats not... ;-;. Asus Ai Suite also reports the same "CPU" temp as Everest, however Asus AI doesn't do "core" readings, just says CPU - Temp 43c....I'm about to start ignoring the core temp reading as with this heatsink there is no way it could spike from 45c to 60c in a second...it just can't be correct can it? I should also note that by just clicking on Opera, or opening a video, my CORE temps will go from say 45c, to 50c within a second as well, they shouldn't fluctuate that much should they? I should point out, that the CPU temp that Everest, and AI Suite gives, is the same temp that my bios gives, however my motherboard dosen't report Core temps in the bios, and the Phenoms only have one temp sensor...so are my core temps more than likely incorrect, thus why they are so spikey and high, also during the everest stress test for one second, while the core temps spiked from 45c to 60c, the CPU temp only went from 43c to 45c... *edit* just did a everest stress, cores went up to 70c, CPU read 54c top, no BSOD or CPU restart...does that mean core reading are incorrect?

I just got a AMD X3 720 a few days ago. Its on an ASUS M3N-HT. So far its running at 3.75ghz, and its been stable. 3.8ghz @ 1.525v gets crashes, but 3.7ghz @ 1.45v has been solid. (18.5x , 200, auto). So far temps are 33c in Firefox, and 44'c gaming/benchmarking. I'm trying out a CoolerMaster V8. I was planning on liquid cooling a AMD 940, but I impulsively bought this setup instead after reading about unlocking the fourth core. I think your cooling fan has a 120mm fan too I'm not sure why your temps are that high. Have you tried the Utils on the Asus DVD? I have a AI Suite program that was included that shows speed, and temps, but also includes a fan controller. Have you tried upping the CPU fan to performance mode? The cooler you have should work better than 60'c. Have you tried mounting your case cooling fans to blow in thru the front, and out the back. I got better results when I stopped cross directing the airflow.
Maybe mine is lower because my 720 X3 has one less core.

I've been playing with Riva Tuner v2.4 for my video card, with much better results when I put the cooling fans at >85%. 100% seems to make more noise than cool. Even at 60% it keeps the the video card cool while GPU overclocking, and no crashes. It took a few tries to learn my way around Riva. In my previous setup, the Nvidia control panel had alot of adjustments. Now I only have a few, even tho it still on 32bit Win XP, and its the same driver version. But no fan adjustment page or temp monitor anymore.

For $40 I'd try one of these:

air flow is not the issue...the heatsink itself hardly gets warm. I can have a extra 120mm mounted directly infront of the heatsink and it hardly makes a difference. That is why I am saying I THINK the core temps are 100% wrong, as they are TOTALLY different than my bios temps, and I've never heard of a proper CPU temp spikeing from 45c to 60c within a second. And on top of that, AMD says Phenom II's have one temp sensor, I'm pretty sure that would be the one the bios would pick up, and the bios one is MUCH cooler and dosen't spike like the "core" temp at all...on top of that, if these core temps were correct, then the Phenom II should have thrown a fault code and restarted when it went past 62c...right?

Reply to RPaulG87

you will probably find that the temp drops after a bios update

Reply to rangers

I already said I have the most recent bios, what I'm asking is should I trust the core temps or just the CPU temps the bios and Asus ai gives off?

i would go with the temps asus ai is showing

Reply to rangers

Ok in that case everything is safe and stable

Reply to RPaulG87

If you pull your hsf again, check and see if the cpu has a crown on it, as sometimes they do, and arent perfectly flat, and dont cool as well as they should, giving a poor seal with the cpu/hsf connection. Have a decent straight edge, go accross the top of the die and hs itself. If so, start lapping

I'm currently running a Phenom II 940 as well. 3.4Ghz on stock settings, with a Sunbeam Freezer as my HS using TX2 paste. As I'm reading things at the moment (I checked the temps from both SpeedFan and AMD Overdrive programs), I'm running at 36c idle doing little things like playing music and cruising the intarwebs. Under load I rarely ever go above 40c, and when it do it's the lower end (Highest I've ever seen so far is 43c). This is playing games like TF2, COD4, WoW and Warhammer Online.

So either your bios is running a bad temp sensor, or the cpu needs lapped. I'd recommend SpeedFan for recording/watching temps as well.

I see nothing wrong with your temps. I've been running those same temps for about 3 years now.

Ok...once again, I think the bios is spot on, the CORE temp readings are what I'm wondering about. Right now the bios temp is at 38c idle, and that's without the Arctic Silver even remotely broken in, what I'm wondering, is where they heck Speedfan, and Everest, are getting these spikey, high temp core temperatures, when the Phenom II only has ONE temperature sensor, which I'm almost 100% is what the bios would be reading, so where exactly are these programs pulling this spikey, high core temps from if there is only one sensor? CPU currently idles at around the same temperature as the motherboard, motherboard is 39, CPU temp is 38, core temps are, as usual, way off and more than likely, very incorrect, they are around 48c

And ZipZoomFly, if those core temps were actually correct, then that would have been seriously wrong, the Phenom II 45nm design is rated for a maximum safe temperature of 62c, 70c and it would go into core meltdown.

Cervani, where are you getting those temps from? Motherboard bio sensors, or core temps?

I should add that just browseing around the core temp goes from say...50c to 54c, where as the CPU temps stays at a steady 39c, dosen't jump around at all unlike the core temps.

I think part of it is due to your case and setup. I say this because mine is almost Identical.

Phenom II 940
Asus M3A32 Deluxe
8 Gigs G.Skill Ram
Thermaltake 750 watt PSU
Thermaltake Armor+ MX Case
2 Radeon 4850 video cards

The bios temperature tends to be lower because the video cards arent active. As soon as I boot into windows and the video cards are active (I run 3 monitors) because the 4850's run so hot the temp of everything in my case goes up. As the ambient temperature in my room has increased (80 degrees outside this week) my processor temps rose from around 43 idle and 50 load to about 49 idle and 56 load. I've stress tested and it doesnt past 60 yet but I'm still at a range I'm not comfortable with. I think alot of this is that while the Armor MX is a good case, it doesnt seem to move enough air when using 2 video cards like the 4850's which normally run hot (even with the fan cranked to 50% my cards run at atleast 70).

Edit* Got some Zalman Super Thermal Grease today, applied it with the brush applicator, instantly a huge difference. Idles around 35c right now at 3.4ghz, quite happy, should also see a 1-2c drop more after it breaks in according to Zalman :D, stuff clearly destroys Arctic Silver 5.

Reply to RPaulG87

2 fans? Thats it? Christ. Am i crazy for having 7 high speed 100cfm fans?

Reply to PsychoSaysDie

Not at all. My current fan count, not including the GPU fan, stands at 9. Two are >150CFM (granted, they don't run that fast normally - I have them on a fan controller).

6 12cm fans on a controller + 1 on a M/B header and I want to replace 5 of the 12's with 14's.

If the heatsink is not hot to the touch, then the temp readings you are fretting over so badly are incorrect.

good point, though I wouldn't really call it hot to the touch - warm would be more my thought of 50 to 60 degrees celcius. I've got workin' hands though.
My 940 @ 3.4 is actually pretty cool. Cooler than my Opteron 170 @ 2.6. Case temp is cooler overall as well.

I don't know what some of you have for cases and videocards but my case has way less fans and runs quiet and cool. I'm a server case kind of guy, though.

The Big Rack makes more noise than anything because all the Cisco's and stuff have obnoxious fans. Most of my servers are mounted there and have small fans except the file server which needs a bit more to keep the SCSI's cool but I don't overclock servers so they are pretty stock. The Phenom 2 box, (the one with the pretty blue fans I spoke of earlier), sets on top of a little 24U rack for NAS, (more fans), but isn't mounted and I keep the other systems in the house bone stock because we have kids so every once in a while we need to boot a ghost disk and start fresh. How do you connect to your servers? It'd be a nightmare for me without a multiple monitor rig and a laptop or two.

I'm on a thermaltake V1 and im @ 40C idle @ 3.6ghz.

Was @ 35C idle before my 200mm fan went.

Suprising as the V1 is supposed to be a very bad heatsink, even the horrid Spinq I had was supposed to be better O.o. Anyway, I OCED to 3.7 ghz @ 1.45 volts, solid, tops out at 54-55c under 100% load in Everest. The Zalman grease REALLY made the temps go down and get solid. I've noticed the heatsink dosen't really get hot @ stock, however when you overclocked and push more volts into it, that sucker definatly gets warmer.

In summary, core temps are way off on the Phenom IIs, AMD didn't even put CORE readers in the Phenom II, it has ONE sensor, and that reading is read in the bios, so I am still clueless as to where Speed-fan, core temp, and other programs are pulling the "Core temperatures" from which are so drastically different from the bios CPU temperature reading.

I have this same problem, 47c on my new phenom 2 940be i got yesterday. I have found that all 4 cores are constantly on 75 - 100% load even when its just sitting on desktop doing nothing no programs runing at all, and from what i have read on this fourm and others, other ppl have been having this problem to and its neather the motherboard or cpu. On 1 fourm i was reading this guy had put his phenom 2 into another motherboard and it ran fine then @ 2% load and 33c temps, no crazy 100% loads and he had put a diffrent cpu in the origonal motherboard and it ran fine to. As it would seem some motherboards and cpus "hate each other" . What views do you guys have on this ?

My specs are

Cpu: Phenom 2 940 BE @ stock with watercooling
Mboard: Asus M3N-HT Deluxe "Latest bios update 2101 i think or 2xxx up from the beta 1901"
Ram: 8 gig ddr2 ocz reapers
Grapics: Gainward GTX 275 "I also got yesterday"
HDD: Segate 500gig 32mb cach 7200.10 RPM sata
SU ocz 1010watt
Case: Thermaltake armour LCS "no heat coming out of the case or in it nice and cool"
O/S: Windows vista ultimate 64bit

Or maybe my cpu or motherboard are just fulty. i have taken a picture of my desktop with task manager showing my loads on all 4 cores but i do not no how 2 post it here so you will have to take my word for it.

But as it would seem i have seen another person with same motherboard and cpu and thay had no problems!

Maybe AMD are punishing me for geting a nforce motherboard and not 1 of their own :p .

Would like to fix this problem then o/c my cpu to 4ghz :pt1cable:

Woot problem solved sorta, basicly i unpluged the pc took my watercooling apart and took the cpu out then put it back in then put the stockO fan cooler that came with the cpu.
Load times are between 1%-5% all 4 cores YAY but my temp has gone upto 50c idle and oveclocked it to 3.4ghz same temp 50c idle :( any sugestions i do live in australia but its winter at the moment 20c room temp right now side of case is open. i might buy some of that zalman thermalgrease cause atm the HSF is very warm so my temps must b on target at 50c 3.4ghz :( idle .....

If its at 50c idle I would be worried. Load that would be ok. Try just just running the stock cooler without the water cooling setup? Also, when you took the cpu out did you reapply any thermal grease?

fisrt this temp in your case or your cpu if is your case temp that meen your cpu is at 90 min stop your pc now second you take a cpu whit not a fan that doesnt help like a verry good CNPS9700 LED of zalman and to use a non fn cpu cooler you need a very good air flow in your case and normal people when they oc thier cpu put water cooling

Hi, I've been reading the forums around here about Phenom II x4 940 BE. I see a lot of interesting stuff, but one thing i noticed, and I'll provide several screen shots if need be. I have an Asus m3a-32mvp deluxe motherboard running the 940, but I am able to hit 3711 megahertz with the cpu multiplier at 1.4125, the front side bus speed is at 200, and the ram i have is mushkin 4028 gigabytes of it at ddr2 1066. I'm also running windows xp 32 bit, so it yes it only utilizes 3.25 gigabytes of the memory... the question is, would it be worthwhile to increase the fsb and decrease the cpu multiplier? (right now I've got the fsb at 200 with multiplier set at 18.5 and it runs stable all cores maxed at 100% with 53 degrees Celcius, using Zalman 9700 led cooling fan with artic silver 5 thermal compound grease, the fan is about 120mm while the entire thing is 150 mm just incase any of you are interested.) Sometimes I feel like my boot up is slow, and im wondering if its because my ratio is 3:8 aka fsb:ram? If i get the ratio to about 1:1 will that increase performance exponentially, or should i just leave my stuff alone in the bios? (i'm quite aware that raising fsb also raises cpu and ram speed etc.) I'm sort of experienced with overclocking but I want to know more to maximize my knowledge and performance without obliteration of the mosfet, voltage regulator, transistors etc.

All I know is that each board and chip are different, but I had stability issues into I did some benchmarks with AMD overdrive, and for about 30 min to an hour i was able to be stable at 1.4125 volts with 200 fsb with multiplier at 18.5x
