Temp Question i5-2500k

[gekin]

Hello,

I recently bought an i5-2500k on a Gigabyte Z68 motherboard and have so far not had any issues. The idle temps hover around 32 degrees and around 50 degrees in games/load.

Today I overclocked it to 3.9 Ghz (I thought that seemed pretty reasonable on a stock heatsink) and it still idles at 32 degrees... however when I tried to run Prime95 the temperatures literally spike right up to 85+ degrees within no more then 10-20 seconds into the test!

My question is.. I know to overclock one should invest in a decent aftermarket cooler but I was really worried at how fast it jumped... I was wondering if anyone had any input into some tips because now I am REALLY worried I might damage the chip. Is it a matter of improper heatsink-thermal application? Faulty sensors (i used HWMoniter and SpeedFan). I just can't see it jumping THAT high just for a 3.3 - 3.9 Ghz OC.

Any help is greatly appreciated. If it's not normal I don't want to waste any money on a 212+ or something and find out there were other issues.

PS: My vCore volts don't change, if that helps anyone here.

Solved. I put the clock back to stock and Prime is running at 60-75 degrees. ()

As to keep the thread atleast worth a damn, anyone here reccomend a good i5 heatsink system to overclock to 4 - 4.5 ghz ?

If all you do is change multiplier, then yes your gonna get high temps even with a aftermarket cooler.
You won't get optimal phase switching and the chip will overvolt itself by huge ammounts, especially once you get north of 4,3/4,4.


Look around the threads, there are various theories to what's best practice.

The less you tweak, the more heat you generate on higher multipliers, and the more any aftermarket heatsink will suddenly seem quite shit.

Buy a better heatsink, others can recommend one i dont know. Dont leave Vcore on "auto" pick a voltage and set it, again others can advise you on what voltages the 2500k is comfortable with.

If you want higher then 3.8 then the 1.30v should be change to 1.36v close to 1.40 to do 4.2Ghz or soo.... my guesses on the voltages.


Also there is no vdrop on sandy so your temps are real.

I cant imagine if you up the voltage how hot things will get, it will go to 100c and what not. Dont OC until you have a cooler made for OC not a stock cooler. The sound of the fan will be loud but the chip will be cooler with a huge heatsink and fan. People use TRUE etc..

I recommend that you stop guessing on what you have no experience with, since your numbers are off a bit.

+1.

My 2500K does 4.44GHz at around 1.25-8 V, along with 1000 others. And no Vdroop? Strange, wonder what those settings on my motherboard do then

I've got a 2500k with GB-z68XP-UDB using AC Freezer 13 HSF.
Back in early Sept I overclocked mine to 4.2ghz running Prime95 which instantly jumps at high 80c.
I then backed down to stock frequency.
Then again my room temp was 80F (hey in Texas).
I will try again when the room temps get down to low 70F.
My case is a HTPC Lian Li (mid ATX) which may even be a factor.

The mobo will add way to much voltage if you try to just raise your multiplier, if you manually adjust your voltages (take it off auto) you should be able to leave it at the standard voltage and be able to get around 4-4.2 ghz and your overheating problems will dissapear. If you get a bluescreen then either up the voltage a cvouple of notches or drop back the overclock by .1ghz and try again.
