i5-2500k running hot

post #1 of 17
Thread Starter 
Hi guys.

Having a bit of a problem with my new sandy bridge build:

i5-2500k
msi p67a-gd53
corsair vengeance 8gb

I'm using a cm haf922 case, and a thermalright ultra-120 extreme and MX4 thermal paste, but idle temps are 52c and rising to 59ish - this is stock speed with no overclocking.

I reapplied the cpu cooler also with different amounts of thermal paste and it made absolutely no difference. I have never had a problem with the thermalright ultra before with my Q6600 and I'm puzzled as to what is going on. I even bought new fittings for my cooler so that the backplate etc matched the motherboard holes. It was quite fiddly to install though, moreso than my Q6600 because of the heatsinks around the cpu area. Also trying the intel stock cooler gave similar results, which is even more strange.

I tried moving the fans around in my case and had all the side panels off but it made absolutely no difference.

It's frustrating because I really want to use my PC but idle temps are too high for my liking and so it's currently turned off while I try to figure this problem out.

Any ideas?

Take a quick look at your voltages either in BIOS or CPUz. It wouldn't be the first time a board detected and applied the wrong voltages to the CPU. It doesn't happen a lot but it's still worth looking into.

^This.

Although even with a lot of voltage, it shouldn't get such high iddle temps.

I can give it a good 1.4v and I'll still get around 30ºC on iddle on my Thermaltake FrÃ*o.

You may want to check if you seated your cooler probably, but yeah, first check motherboard's BIOS for voltages.

Where can I get a list of the stock voltages for the i5-2500k so that I can check whether they are correct?

turn off "cool and quiet" and LLC first, as well as any other power saving options in the bios first edit: 0.988v is the stock voltage for an i5 2500k
I found this arbitrary thread while doing a google search for your voltages. Check to see if the voltage is being detected anywhere near that number and it'll give you a good idea of what you need to do next. Most likely if the VCore is cranked way up then the rest of the voltages probably are too.

Pretty sure that's not correct. CPUs have a "range" of available stock voltages, or "VID"s.

0.988v is the stock voltage for an i5 2500k.

The thing you are talking about is called Vdroop. The voltage for the 2500K is 0.988, as in the number you enter.

Just out of curiosity, where are you pulling your temps from? BIOS or 3rd party?

No, I'm not talking about Vdroop. I'm talking about VID. They're not even related.

And VID is -not- the same on every chip in the same lineup.

Don't have time to find a perfect source to explain, but google brought me these threads

http://www.overclock.net/intel-cpus/...t-cpu-vid.html Look at post # 3 and 4.

"The VID is part of the uCode that the chip is imprinted with when it leaves the factory. Each chip's VID is different based on its results with Intel's testing processes. What the VID is supposed to do is tell the motherboard, "Hey, this is the voltage I require when the FSB is set to default and the voltage setting is 'Auto'." It varies from chip to chip, as each chip has different tolerances and requirements based on the fabrication process not being 100% perfect. "

And this thread (Edited this one out, wasn't what the link said it was. )

Look at this link from Intel. See where it says "VID voltage range" http://ark.intel.com/Product.aspx?id=48496 That is the range of possible stock voltages for my CPU. My particular i5 760 has a VID of 1.15 vcore. They are not the same from chip to chip.
