intel 2500k - Need to change thermal paste?

post #1 of 10
Thread Starter 
Hey guys,

I've been generally happy with my Noctua but after running a routine check with prime95 lately, I've been getting 62*C average on a stock i5-2500k. I have read around google and those temps are consistent with people running it at 4.7Ghz, while mine is stock at 3.4Ghz in full load.

I ran out of thermal paste otherwise I would've just done it without asking, but. Apart from thermal paste, there couldn't be any other issues with the Noctua? Right?

EDIT: In case people have rigs disabled, I'm reffering to Noctua NH-D14. The idle temps are ~40*C. I also have no idea about ambient temperature, I'd say normal living room, not too chilly but not that hot either.

It is a bit high for stock but not dangerous at all.

Idle is normally high 20's to low 30's
Stock on 100% load i have no idea but i would estimate between 50 and 55 degrees

Pretty bad for stock. Are you on auto voltage?

I'd hit a max idle of 40C with 1.32v 4.5ghz oc speedstep disabled. Same cooler

Ambient temps will certainly have an effect on idle and load temps but as others have mentioned, unless your ambient temps are 30c, your temps do seem higher than normal.

Okay guys, I'm going to buy some thermal paste tomorrow and report back. Thanks.

I went to the store today and purchased the Z9 as it was the most high-end paste they had. The temps are now steady at 58*C in full load and they should go down after a few days.

Actually Z9 is high-end but it's performance for proper aftermarket heatsinks is not ... It does poorly with most contact pressures of those heatsinks with good mounting mechanisms

Okay after a few days(4), I am now running a 57-58*C full load temps. The idle temps are around 40*C.
