Just installed a Q9550 into dx48bt2 that previously had a E7400 that ran fine good temps .I plunk this big quad in and Im seeing high 60's across all four cores but bios reads mid to high 40's.Can someone PLEASE tell me if im screwed up or is this all just fine??.Ya im being real paranoid seeing as this is a significant jump for me.Bios has been updated im using real temp and everest for diagnostics.There are all kinds of fans in the case 3- 4" and an 8".Repasted hs with arcticsilver.I think all bases are covered unlees someone else has input that iam overlooking.



Thanx in advance

it is slightly high, they mostly stay at low 60s to high 50s,

to be safer, just recheck everything and make sure u have good airflow so that the air comes in and goes out

WooHoo U just made my day bud.Time to have some fun.But not to much fun.That costs too much money.Would u recommend a aftermarket fan nothing to crazy.

the one that came stock out out of the box.I dont plan on working this thing to hard but at least get the temp. down better than this stock Intel rig.Something without these goofy push pins would be swell.What kind of spaces.Huh?

Ya i am willing to spend between 50 and 100 bucks.That should give me a few more options.The link u sent though i do appreciate it is almost identical to the stock one.I read somewhere that a floe threw scythe works well for My application.What do u think???

So I'm posting a photo of the readings from real temp from My q9550.They actually come don a couple of degrees since re pasting with arctic silver. All other diagnostics (Everest, cpuid) are all very similar.I realize someone has posted that these stats are acceptable but , I'm just not use to seeing these kinds of numbers especially coming from a dual core . I don't know at this point what will put my mind at ease but some reassurance would help. Thank You

Just copy and paste the url.I'm trying to figure out how I could by a cpu off the shelf with the required fan installed with proper air movement and get numbers like this?If u get the pics working I will send more of my rig.Should i see these numbers as soon as i boot up? I just cant help but think that something else is wrong .Is there such thing as a sensor test? How can Intel justify selling a fan cpu combo with unsuitable standards not to mention the price.Is this just something that u deal with running this hog and if so .Could u tell me if i could get accurate readings on the cpu tyemp with an infrared temp gun?What kind of voltage should be running to the processor .Maybe default is to high probably a long shot.

majorRager,

Your temperatures aren't even close to being a concern, however, you can't draw any conclusions until you properly test your rig.

Overclocking and temperatures are all about specification, so it's very importent to be specific, otherwise temperatures make about as much sense as comparing apples to oranges thermal fruit salad in a blender! :pt1cable:  For everyone's benefit, I am posting the following information. My objective is to assure that enthusiasts understand Intel's specifications, standards and test methods, so they can better decide how to apply and manage their overclocking options.

From Intel's Processor Spec Finder - http://processorfinder.intel.com/details.aspx?sSpec=SLB...

Q9550 E0 and C0 variants:

Vcore Max 1.5v
Tcase Max (CPU temperature) 71c
Tjunction (Core temperature) 76c

From the Core i7 and Core 2 Temperature Guide - http://www.tomshardware.com/forum/221745-29-sticky-core...


"Section 1: Introduction

Core i and Core 2 processors have 2 different types of temperature sensors; a CPU case (not computer case) Thermal Diode centered under the Cores, and Digital Thermal Sensors located on each Core. The case Thermal Diode measures Tcase (Temperature case), which is CPU temperature, and the Digital Thermal Sensors measure Tjunction (Temperature junction), which is Core temperature. Since these sensors measure 2 distinct thermal levels, there is a 5c temperature difference between them, which is Tcase to Tjunction Gradient. Core i7’s / i5’s and Core 2 Quad’s have 1 Tcase and 4 Tjunction sensors, while Core 2 Duo's have 1 Tcase and 2 Tjunction sensors ...

... The monitoring utilities provided by motherboard manufacturers monitor CPU temperature, while some popular freeware utilities monitor Core temperatures ... Real Temp ... is recommended for users interested in monitoring Core temperatures only ... SpeedFan monitors Tcase (CPU temperature) and Tjunction (Core temperature) ... "


The Thermal Specification shown in Intel's Processor Spec Finder is Tcase Max (CPU) not Tjunction (Core), which is a very common misconception among most enthusiasts. Since there's a 5c gradient between the CPU sensor and the Core sensors, (shown in the following Intel document) - http://arxiv.org/ftp/arxiv/papers/0709/0709.1861.pdf - just add 5c to the value shown in the Spec Finder to determine the corresponding Core temperature, which is 76c for the Q9550 variants.

Intel's second and frequently misunderstood Thermal Specification, Tjunction Max, (100c for the Q9550 variants) applies to overtemp protection such as Throttle and Shutdown, so you don't toast your transistors. As such, any Q9550 temperatures which exceed 76c should be considered "overtemp". Further, when specifications are exceeded, then processor degradation becomes a concern, which is explained in the following AnandTech article - http://anandtech.com/cpuchipsets/intel/showdoc.aspx?i=3...

Prime95 Small FFT's is the Standard for processor thermal testing, because it's a steady-state 100% workload which yields steady-state temperatures, whereas Blend is a memory cyclic workload which yields fluctuating processor temperatures. Small FFT's will reach 97% thermal saturation within 7 to 8 minutes, so a 10 minute test is adequate. Thermal testing should be conducted as close as possible to 22c (72f) Standard ambient, with case covers removed, the computer clear of any desk enclosures, and all fans at 100% RPM to eliminate cooling variables, and to produce consistent and repeatable results for comparisons. If the Gradient between CPU temperature and "mean" (average) Core temperature is not ~ 5c, then BIOS is incorrectly coded. CPU temperature and Core temperatures can be individually calibrated in SpeedFan by following the Calibrations Section in the Temperature Guide.

OCCT and Burn Test (reminiscent of TAT) use LinPack, which shows thermal signatures that resemble the ups and downs of a bad day on the stock market, and cycle between light workloads, through test segments which spray all processor registers with all one's, (100% thermal load, which equates to 115% workload), and can push an overclocked Q9550 at Vcore Max 1.5 right on past Tcase Max! :o 

Since there are very few applications or games that will spike, let alone sustain processor workloads beyond 70% to 85%, utilities which load all registers with all one's are not representative of real-world computing. While these utilities are certainly very useful for stability testing, they are inappropriate for thermal testing. The 3DMark benches are excellent for stability testing, as are applications for ripping and encoding.

To make sense of CPU temperature and Core temperature, compare them to a 4 cylinder car that has 5 temperature guages; 4 of the guages are cyclinder head temperatures (closest to the heat source), and the 5th guage is the overall engine temperature, which is 5c lower than the other guages, and is the temperature guage with which we're all familiar. We know that red-line for the Q9550 is 71c (Tcase Max) on the engine temp guage and 76c (Tjunction) on the cylinder head temp guages, but if we push the engine too hard and peg all the guages, (95c Tcase overtemp / 100c Tjunction Max) then the engine will shut down.

If you'd like to learn more about processor temperatures, then just click on the link in my signature.

Hope this helps,

Comp :sol:

Thanks very much for the thorough reply.You can probably understand my skepticism when someone says ya go ahead no problem its fine with nothing to back it up.But and I don't mean to be disrespectful you said that there was no cause for concern when I first dropped the CPU in and temps were hovering in the high 70 low 80s but Your info. states that Quote"As such, any Q9550 temperatures which exceed 76c should be considered "over temp".again I am very grateful for your info. most invaluable but there was validity in my concern no the less.I wont take any more of anybodies time for know until the next issue arises because the issue ended up to be a defailt bios voltage issue .Ive been just sitting here staring at realtemp with a smile on my face .Low to mis 30s.Sweet.Again thanks thanks thanks.I will also try Prime 95 for 8 to 10 min. test as suggested in your reply.

Best Regards

When the quad was first put in on friday it was running in high 60s low 70's.I should have kept the pic. your gonna have to take my word for it.All is well now though.Actually check the pic in the 8th reply it shows the readings before I fixed the problem .There are a couple of issues I would like u to clear up for me if u could though.First- when the q9550 was first installed the temp in bios read around 22c to start slowly climbing like it should until it leveled out at mid to high 30's, but all software |(real temp, Everest)was reading low to mid 70's hence the pic.Is there an explanation for this discrepancy.Second-Now after I set the bios back to default the temps. jive.Could it have been that my os was still reading the E7400 temps.

That link is corrupt, so I have no way of knowing your original temperatures.

Keep in mind that no temperatures can be below ambient (room) temperature. Also, BIOS reads CPU temperature only, which function independently from Core temperatures.

84c @ time stamp 10:20:36
Load = 1.7%

This is typical of a stock Intel cooler or an after market cooler which is not properly seated, and has at least one push-pin that isn't inserted completely through the motherboard.

Yes that could have very well been the issue.Not a big fan of the push pins.The fan that came with the core duo the picture shown here /
http://img21.imageshack.us/img21/1336/1002203p.jpg was different in that the raised ,circular ,copper is absent.This slite difference caused a bit of trouble with one of the push pins.an inordinate amount of pressure was needed for it to click.Still doesn't answer why suddenly the temp. drop.I thought occurred to me last night .When I first installed the core duo 8months back I had similar temp. issue that dissolved in a similar fashion.Almost like a break in period.Whats the chances??If it was the pushpin issue wouldn't I still have trouble.Maybe I'll try to get u up to speed.#1-Installed Q9550.Temp. were cause for alarm bringing me here for answers.I was use to seeing 30deg. temps so I was very disappointed.#2. Removed the cpu in hopes that it was a seating issue and killing 2 birds I could clean of stock paste and reinstall arcticsilver.Boot up showed little improvement .So I posted the temps. and someone had replied that there wasnt a concern with these numbers stop being paranoid.I was apprehensive but optimistic that if I kept poking around someone would reply with solution.#3 Intel site forum .A couple of posts led to the default bios settings last night.Reset them and voila! temps. are normal.So the issue might well have been a number of things.Is there an aftermarket fan that does not rely on pushpins but when installing I will not have to remove the mobo.Quiet and low profile are asset.

(1) Why low profile?

The larger coolers all have 120mm fans, which spin slower, and are thus quieter. If you have a narrow case, and cooler height is a problem, then here's the best 92mm fan cooler: $21.99 - Xigmatek HDT-SD964 - http://www.newegg.com/Product/Product.aspx?Item=N82E168...

(2) Why not remove the motherboard?

If you don't want to suffer push-pins, then there is no alternative but to remove the motherboard so you can install a proper retention bracket: $7.99 - Xigmatek ACK-I5363 - http://www.newegg.com/Product/Product.aspx?Item=N82E168...

I think I'm going with the Corsair H50.The review that I seen showed on I7 stock Intel cooler at hi 80's at 100% load.H50 at mid 60's at 100%.Plus it cleans up the case quite nicely.Ya I'll have to pull the motherboard but that will give me a chance to route and sleeve the rest of the wires.Also the fan that is included will pull into the case so I'll have to reverse one of the other case fans no biggy.Heres a pic.It doesnt come with that nvidia fan contraption. http://img5.imageshack.us/img5/3747/corsairh50.png

The H50 is merely a mediocre liquid cooling solution which simply overlaps with high-end air, but certainly isn't any better. Also, understand that it's fan is designed to push warm exhaust out of the case, so you shouldn't be trying to reinvent that particular wheel.

Also, liquid cooling isn't exactly install-and-forget; it requires periodic maintenance.

Just to clear up some misconceptions, here are a couple of photos; http://img248.imageshack.us/img248/5720/h50post.png I'm really set against having a conventional cooler .There so obtrusive looking like something that should be in my furnace's plenum.There something to be said for the H50's compact stature ,making way for better airflow to other components in the case.Having the airflow pull into the case will work out good .You see I live in Canada where I can utilize cool temps.My case backs up to a window which I can run a small duct to.Imagine pulling -10c air across the cpu chillin.

On a different note , have You really been a member of Toms Hardware since 1970??

I personally don't want warm CPU exhaust blowing into my case, increasing the temperatures of my motherboard, overclocked memory, northbridge and southbridge chipsets, overclocked graphics card, 10,000 RPM hard drives, optical drives and power supply. The consequences won't be immediately obvious, so think about it. Some enthusiasts modify their case to mount the radiator outside the rear of the case, sandwiched between push-pull fans, so as to pull air out of the case in a normal direction.

Also, under certain conditions with your window duct idea, you can cause other components to condense moisture and short out. Moreover, consider the effects during summer months. Regardless, liquid cooling will eventually leak ... somewhere. Utimately, t's up to you; so if you like it and want it, then just buy it.

No, I haven't been here since 1970. As you become familiar with other long time members, those of us who are 1970 have simply been here since before the software was screwed up upgraded :heink:  a few years ago.

You raise some very valid points .I guess I should just stick to the conventional and not try to in Your words"Reinvent the wheel" After I thought of it minute the condensation thing popped up.I to am running a VRaptor.The push pull idea is interesting but gets away from my goal of keeping down the noise.

Hi everyone, I'm having some overheating issues with a Q9550 and am going to apply new thermal compound and buy a case fan. My questions are:

1) If I wanted 2 case fans, where would the second one connect to on the mobo? There is only one CHA_FAN connector (but also a PWR_FAN connector).

2) Should the Core 0 & Core 1 temps be almost identical? Mine are always 3 - 5C apart.

Thanks.

Core temps should be similar to each other, but if one core is doing more processing than another core, then it's pretty self-explanatory.

As for case fans, you can connect them directly to your power supply with the 4-pin molex connectors.
