High CM04 temps on nocona 2.8

[earion]

Hey guys i got a Cooler master E3w-NPTXS-04 from orbitmicro for my nocona 2.8 on a ncch-dl... Apparently they are very popular for these processors.
I'm starting to wonder why since i'm getting 75 degrees (celsius) idle. I'd like to compare temps with you guys and if anyone has any tips as how to get this temp down, it will be more than welcome of course !

Yeah, you definitly have something wrong because my friend with stock coolers gets 54 @ load on that very proc.

You could have a defective part.

Did you use all the proper thermal grease, clamps, etc, to secure the cooler?

Take a look at that. In there I have some info on problems that could cause high temperatures.

Is the CM04 the CPU's internal diode? Because if that was not and was a socket temp, you would probably have some things to worry about running it that high.

Is Nocona an E0 2.8 Xeon? I am not to sure. I could be wrong as Intel has not updated their site recently. Anyway, an E0 2.8Xeon has a thermal spec of 72°C according to Intel. I would try and keep the CPU diode about 10 degrees below that under load so if something goes wrong you will still be safe. The CPU can most likely take temperatures a good 50°C higher than that, but the risk of it dieing is much more likely and I for sure would not want to run it consistently at a higher temperature. As long as you keep the CPU's diode/thermister/whatever below that limit of 72°C, you are within warranty (considering nothing else is being run out of specification).

Are you sure you used the right length spacers on the plates you installed under the motherboard? If you used the longest set, it's possible that the heatsinks could be firmly attached to the plates but not even touching the processor. It sounds like this is the case and the processor is hitting its thermal throttling limit.

The 04s are great heatsinks. With a little fan action, my 1.6LVs overclocked to 2.8 are running at less than 40 C idle.

are you using fans with those heatsinks?

usually case airflow alone will not cut it with the coolermaster heatpipes...i used a couple of long screws to attach 80mm fans to each one...

my temps do not exceed 46C under 4x prime95 load with 27C case temps...

well i did not use any thermal grease, just the one that came with the heatsink. I know it makes a difference but not a 40 degrees difference !
i have to check the spacers, that might be it. Because the heatsinks are very thightly attached, and i still get terrible temps.
But if it was the spacers, the heatsink wouldn't even get all that hot, wouldn't it???
My case is totally open, and i have the intel stock fan running on top of the o4...
Do you guys know of a way to check the temps on windows with the ncch-dl ?? Tried speedfan but it doesn't work (gives me a temps of 10 degrees c)

Well, here is a good test to tell. Touch the heatsink. If the heatsink is uncomfortably hot, then you know the heatsink is making decent contact with the CPU and it is another issue. If it is just warm, closer to room temperature type of warm, then most likely the spacers are the problem.

Now is this a CPU core reading or a socket reading you are getting these temps from?

[earion]

i took the fan off yesterday and touched it a couple of minutes after. The thing burnt my finger, so i guess it's not a spacer problem.
The readings i get are from the bios... so i'm guessing it's socket ??
Is there a way i can get a diode reading ?

[@md0Cer]

Not sure. Some motherboards support it, some don't.

If you could tell me all the temperature readings you see in the BIOS, their names, and what they read, I could probably tell you if you can read via the diode or not.

Well, it would be quite hot if you touched it a couple minutes :eek: after no matter if it was making good contact or not, if you just reached in and touched the side of the heatsink while the fan was running and it was really hot, then it is another issue.

I would make sure the voltage and clockspeed for the CPU are at what they are supposed to be at, and make sure the fan isn't dieing.

I cover some of this stuff a few posts down in here: http://www.ocforums.com/showthread.php?t=329015

Also check to make sure there isn't a bunch of dust in the heatsink. Gotta run, ill be back later.
