Conroe E6600 temp: 47c - idle. 72c - on heavy load..

August 25, 2006 8:10:26 PM

Looking for advice.

Yesterday, I have build my first system. Motherboard ASUS P5B (vanilla).
Processor: Conroe E6600.

Actual components list:
NewEgg wishlist = buylist

Stock speed, stock heatsink & fan.

Case has 4 fans... good airflow.

First time when entered BIOS I saw temp around 45-47C. Seems a bit high for idle.

Today I tried stress test my new system. I ran two instances of Prime95 for about 5 min.
Temp raised to 66c (according to ASUS prob). Core Temp beta showed around 60c.

After that I pulled heatsink, placed it back - hoping for better contact/position.

Run two instances of Prime95 again. Now temperature raised to 72c (ASUS probe), at that point I stopped test - just scared of burning processor... Core Temp beta reported ~69c at the same time.

So, now I am just frustrated and do not know what to do?

Should I purchased another cooler or give another try to pull heatsink out and place it back?
When I pulled heatsink out and place it back, I did not use any thermal paster or anything...

Any thoughts, advices?

Btw, I searched forum, but I did not see that people were hitting 72c mark..

Thanks

First, you need to re-apply some thermal grease on the cpu. Use a high quality grease like artic silver 5. Make sure you wipe off any of the old grease on the cpu and hsf first.
Once you have the hsf properly installed, start your system up and check your fan speed. It may just be spinning slow. If it is go ahead and get you a good fan from Zalman, they seem to cool the best.

I haven't seen temps above 50 (ASUS Probe as well) with two instances of F@H running for 8 hours (100% CPU usuage), usually I would say I get 48 or 49 at full load (and this seems to be a tad high compared to other temps being reported by others).

I would say that you do not have good contact with the CPU/fan, as the previous poster suggested you should reapply thermal paste after cleaning and re-mount the heatsink and fan. If you remove the heatsink you NEED to clean and reapply before replacing the HSF.

Have you actually pushed the 4 pins from the cooler in the motherboard?? (it needs quite a bit of pressure to get the 4 pins in good, a small push isn't enough)

I think your cooler doesn't have the contact it needs with the cooler

Well... thats one problem. The thing is, when you place the HSF on the top of the CPU, you basically create an air tight seal, for heat to transfer through.

Since you broke that seal, it needs to be redone. Unless its a thermal pad, it might/should be reusable. The 4 pins I read are a pain to get on correctly.

If your looking for something of a decent price/performance ratio for a HSF, I'd recommend the Freeze 7 pro.

Most likely the CPU HSF is improperly mounted

In addition to the possible solutions posted by others, it is a common mistake that adding more fans to a case will increase cooling of components. If done correctly, yes it will. If done incorrectly, you can actually reduce airflow to/over your CPU and chipset HS/Fs as well as your expansion cards.

If you are a first timer, and unfamiliair, check your fan orientations. If you have a lot of fans, putting them all in parallel flow (i.e. either all sucking or all blowing) is not the best solution.

If you have a ducted case, that is a case with a duct specifically for porting air to the CPU, insure that the fan (if it has one) is "sucking" from the outside, or feeding to the CPU HSF. If you have fans located at both the front and rear of the case, and the case is not ducted, orient the fans in series, that is the front fans pumping into the case, rear fans pulling.

Thank you everyone for advices.

I will try first to re-apply thermal grease.

Couple related questions:

A: Does use of Arctic silver thermal grease will void my warranty on processor?

B: Does use of non-stock cooler will void Intel's warranty on processor?

Thanks again.
August 25, 2006 11:21:56 PM

1. No
2. No

If it voids your warranty, who will bother to buy those after market cooler? The warranty only void in case of improper use of voltage increase.

When you remove the heatsink the thermal material will peel off so your gonna need some more. AS5 will do just fine. If your in a pinch get generic stuff from radio shack, not the best but better than nothing. When I mounted my heatsink I did it with the board out of the case to make sure it was properly mounted. Stock intel 775 coolers can seem to be mounted solidly yet when you look at the back side of the board you will find the pins are not extending all the way through.

Quick Update.

I bought Arctic Silve 5 in local CompUSA store this evening.

I have pulled HSF off, wiped old grease, pulled processor, wiped old grease. Then I dropped ~rice grain of AS5 on processor and put everything back...

It somewhat helped. Idle temp on first startup was showing ~41C. Though about 45C on next ones.

When I ran 2x Prime95 (100% load for both cores) for about 10 minute, the temperature raised to ~59C (according to Core Temp beta) and ~63c according to ASUS Probe.
So, it is better then 72c for sure, but still looks high.

I did not pull motherboard out of case when I installed HSF. I guess, I should make another attempt when MB is laying on the table.

I have a very hard time with putting straight down HSF on processor.
The 4 plastic pins contact motheboard first... Even in this time when put HSF on processor, it was somewhat bumpy - no straight sit...

Is there good technique for putting HSF down in one move?

Any advices are greatly appreciated.

One more thing: I noticed that even when ASUS probe shows red mark temperature 60c, the CPU fan speed is about 1900 rpm. To my understanding it is not maximum fan speed... Any thoughts on this matter?


Thanks.
August 26, 2006 6:38:10 PM

Another update....

I took Motherboard out, pulled HSF, pulled processor, cleaned everything, applied AS5 again... Put everything back...

This attempt make it worser than previous one...

Now Idle is around 42c/45c (Core Temp/Asus Probe).

2xPrime95 for couple minutes = 66c/70c (Core Temp/Asus Probe)

Doh...

I guess I will give another try this evening withou pulling MB out. Because this time I felt that HSF did site down straight...

Is there possibility that ASUS P5B motherboard affects readings somehow? T
hough to me Core Temp should disregard BIOS/MB and read straight from proc...
August 26, 2006 6:55:27 PM

When you take the cooler off your cpu, can you pull it just off or do you first have to turn those 4 pins so you can take it off the mobo?
Don't forget to turn those 4 pins back before you place the cooler in the mobo so it can get tight again.

I'm still in the impression the cooler doesn't have the proper contact with the CPU

A: B: yes and yes. I called intel last year and they said that if you replace the hsf with an aftermarket one, you have voided your warranty (It might even be in the instructions). Just don't let them know if you call tech support. :wink: If you don't screw anything up yourself and the proc looks like it had the original hsf, you will be okay. Tons of people do it, and intel doesn't care if they don't know.
August 26, 2006 7:43:07 PM

Not this again... :?

It should say it in the warranty it self, which I didn't find anything saying using a 3rd party HSF or compound that would void the warranty.

I did find pdf files which defines the 3 year warranty, found here:

Processors - 3 year Limited Warranty

I really don't see how installing a 3rd party HSF can void the warranty, especially if it was designed for the socket. Nor did I see anything about specific thermal grease, compound, or pad.
August 26, 2006 7:48:18 PM

In all reality it dosn't matter. How is intel gonna know if you did it anyway.
August 26, 2006 7:54:06 PM

It prolly will matter to those who somehow screwed up, or for some reason the CPU did fail.

Again, if using something like AS5/3rd party HSF void warranties, then they should put it on their website and products to warn users, which I still yet to see.
August 26, 2006 8:16:52 PM

How is intel gonna know whether you used their supplied HSF or one you bought aftermarket?
August 26, 2006 8:19:06 PM

It's not going to matter, since they don't specifically say what 3rd party HSF used, or compound.

Edit:

And when I said, "It prolly will matter to those who somehow screwed up" I was talking about those who worry about the warranty.
August 26, 2006 8:29:25 PM

I accidentally overvolted(2.0v) my E6600 yesterday while overclocking. Temps went up to 70c lol. Hope it didn't damage it :p 
August 26, 2006 8:34:29 PM

I've been building computers for over 10 years and I've only burned up one cpu and it was because I tryed useing a celeron HSF an a Duron and AMD replaced it. I doubt they get many returns and unless it is physically damaged they probably ship out a new one.

Well.. as far as warranty, it does say:

Why.. would you do that? Put a celeron HSF on a Duron? Cause you been building computers over so many years, and thought it would work?

Now I can understand perhaps a cheapo type of CPU, but if you spend 1k on an E6800 or 800 bucks on an FX-62 CPU, and do the same thing, I bet more question maybe asked.

Edit:

But then answering those questions to avoid the embarrasment would require you to lie.
August 26, 2006 9:25:15 PM

That was before amd started putting caps on their cpus and you needed a special shim. I just forgot until it was too late. Yes it was a $40 part so I doubt too many questions were asked.
August 26, 2006 10:58:55 PM

when you say you put ~rice grain of AS5 on did you spread it around? and yeah dont forget to make sure like 100% positive that those pins go all the way through and latch in. also you do need a pretty decent coating of AS5 on the proc so make sure you spread it and have an even coating on the whole surface.
August 26, 2006 11:10:09 PM

Actually, I did NOT spread the compound, because the AS5 instructions does not say that I should do it for P4/Athlon...

But I will try the technique with spreading tonight.

Arctic Silver instructions


Another thing, when I pulled HSF after my first attempt with AS5, the spot size was about a dime, whereas heatsink is about quarter size.
The last time I put slightly more of AS5, hoping it will spread may be more in size...

Well, I will try manual spreading today. Thanks for advice.
August 27, 2006 1:12:03 AM

ive never read the directions ive always just put an even coat over the CPU. also how did the stock thermal grease come in 3 little patches like mine did or was it just a single spot? because my stock HSF had like 1 rectangle in the middle and 2 trapazoids on the sides that when tightened down good spread over the whole thing. also when spreading the AS5 make sure you dont get air bubbles in it. and what aare you cleaning the stuff off with because you want to make sure you clean the surface with alchohol or the like so the thermal compund dosent emulsify with whatever cleaning solution you used.

P.S. Ive put AS5 on many athlon XP chips and ive always gotten cooler temps when i spread it. i didnt use it on my E6600 as my temps with teh stock stuff are only in the 30's
August 27, 2006 1:26:19 AM

Exactly. Zalman is the best. No thermal grease = very bad idea.
August 27, 2006 3:40:25 AM

Another update and happy ending. Temps below in format Core Temp/ASUS Probe.

I have re-applied AS5 third time. Turned on system...

Idle temp: 39c/43c
2xPrime95: 63c/68c after ~ 5 minutes.

At that point I was quite disappointed with results.

Then I tried check the plastic fasteners. Tried pushed a little harder without pulling processor out. Pressed hard on on one, then another, and then I pressed quite hard on pin closest to CPU FAN mb contact... And I heard quite load crack sound... I thought sh%t, I broke my motherboard....

Immedeately turned on system, to check if it boots... And it did boot!

And what I see now?
Idle: 33c/37c
2xPrime95 after ~15 min: 48c/51c!!!

So, i guess that crack sound was final snap of the pin.. It was pretty loud to me...
Good part is that processor gets proper cooling now. I am quite happy about that.

Thank you very much everyone for advices and recommendations!!!!

I just put my computer togather today. Poped Fan in all the way( very hard) The artic silver instructions say_____ Thermal pads can be scraped off with a plastic tool that will not scratch the bottom _____ is that the 3 little rectaingle and trapizoids on the stock heat sink? :D  My 4400 temp went to 68C During bios(load 66min) Asus probe 2 after like 4 hr reads CPU 56C MB 45C. Been adding programs tops 61C then goes down to 53-56ish C .... Stock heatsink with artic silver 5... The cpu fan has not hit 3000RPM... It goes to 2770-2975RPM What else can i do to lower it? :?

My first built computer i dont know much. help thanks :D

That's the first thing i learned while building my system. You can't be afraid to apply pressure. When i first put my cpu in i had to use quite a bit of pressure on the socket leaver to fix it in. I was initially worried incase i damaged it :p  I also had to use alot of pressure to fix in the last screw for my zalman 9500-AT hsf. But i think that's to create a air tight seal.

I did spread around AS5 somewhat. Not completely over the entire surface though. Because the hsf so tightly fixed to the heatspreader i imagine it gets evened out further across the surface.

just make sure the 4 pins have clicked and you should be fine :) .
A motherboard is strong enough for the pressure you have to use for putting in the pins for the cooler.

Processor: Conroe E6600.

Actual components list:

First time when entered BIOS I saw temp around 45-47C. Seems a bit high for idle.

Temp raised to 66c (according to ASUS prob). Core Temp beta showed around 60c.

After that I pulled heatsink, placed it back - hoping for better contact/position.

Run two instances of Prime95 again. Now temperature raised to 72c (ASUS probe), at that point I stopped test - just scared of burning processor... Core Temp beta reported ~69c at the same time.

So, now I am just frustrated and do not know what to do?

Should I purchased another cooler or give another try to pull heatsink out and place it back?
When I pulled heatsink out and place it back, I did not use any thermal paster or anything...

Any thoughts, advices?

Btw, I searched forum, but I did not see that people were hitting 72c mark..

Thanks


first .... don`t trust entirely the motherboard readings....from different reasons the temperature shown there (in bios) may not be entirelly accurate......

if you are really concerned about your temperatures ..use an electronic termometer ... try to place the termocouple as close as posible to the cpu...\


from my experience ... asus readings are not accurate with the intel cpus (unknown reason)...but not a general rule .....
other brands like gigabyte give you enough accuracy ..but not a rule ...
example ... one cpu placed into a gigabyte mobo ...the temperature reported was 40 degrees...the same cpu into a asus mobo ... the temperatures shown were 20 or more degrees higher .....
the electronic termometer proved to be closer with the gigabyte readings...

i`m not saying that your asus mobo sensor is totally wrong ..but you should check with others and preferably use a digital termometer

good luck
