View Full Version : Is my i5 2500k running too hot?

I have an i5 2500k with a stock cooler.
Idle temp: 29-35 C
Playing Minecraft (Normal Render): 45-52 C
Playing Rage: 48-53 C

Are those temperatures to high?
Should I get a new Cooler?
Should I try a different brand of thermal paste e.g. Arctic Silver? I used Z.P. Thermal Paste

I did applied the thermal paste in the correct fashion: Drop a BB pellet sized thermal paste in the center of the CPU, mount the Cooler
at a perpendicular angle and locking down the cooler securely with no movement whatsoever.

Don't seem unduly high to me, but then my wee netbook (eee pc 1201n) runs at 70 to 80 and that's normal for it.

Wow!
My BIOS recognizes that as dangerous/abnormal!

It's a known issue with these but short of drilling extra vents in the base, not much can be done.
We have 2 of them and neither has any issues so I won't worry until a HDD fails or something else forces me to strip it down.
Then I'll get me wee drill out! :D
Would possibly be a bit warm for a tower though.

No that's fine, mine ran at about 65 C under prime 95 stress testing at stock with stock cooler. Dangerous temps are in the region of 90 C + but if it went over 70 in normal use I'd get a bit concerned. It's actually fairly hard to damage them from a short burst of heat, they'll shut the system down if they hit the danger threshold.

At 4.1Ghz using an Antec Kuhler water cooler it hit about the same as above - low 60's under stress test. My current 3570K is using a Hyper 212 evo and @ 4.2Ghz is hitting the high 50's occasionally getting into the 60's

I had an i7 920 a while back, sold it after 2 years and in the process of rebuilding for sale discovered the stock heatsink had never been mounted properly - one of those stupid plastic clips didn't engage. A bit of testing confirmed it had been running 10-15 C hotter than it could have been - for 2 years of rock solid gaming duties......

Which leads me to my tip for mounting intel stock heatsinks, especially when reusing. Look at the white plastic bits that go through the motherboard and ensure they are all pulled down completely out of the black piece as far as they can go without forcing anything, sometimes they stay partly up inside and will not clip into the motherboard like that.

Another thought, you mention applying thermal paste. Did you remove the factory thermal compound and use paste instead? the stock cooler comes with it pre applied and you just stick it on. Perfectly adequate if not overclocking.

iirc 72*C is the max design operating temp for the 2500k. so you're fine.

I did use it at first but I think I stuffec it up when putting in the cooler. I put it in on an angle. Then I lifted it up again to check blah blah blah.
So I put new paste on. (after cleaning the CPU and heastink with alchohol of course)

Oh and another thing, things seem to lag more - marginally.
Do I have to wait for the games to get used to my new specs or something?

This. Any higher and your computer should automatically downclock your cpu to lower temperatures. Unless of course you have disabled it.

Is this compared to your old althon system?

Yes compared to the athlon system.

did you bump up the settings at all? Your gpu will be bottlenecking your performance and chances are bottlenecking your old system too.

No settings bump at all.
Skyrim lags more. I had it on medium and still do. Rage works WAY better, Minecraft on highest works fine (no far render, needs 64 Bit Java)
Mass Effect 3 lags just a fraction on highest settings and the same with Burnout Paradise.

Hyper 212 evo all the way, so cheap and so effective as long as your case has reasonable airflow.

I was hitting a bootable 4.3ghz with my 965 under an evo 212. Just 0.1ghz off of a 1ghz overclock. Want to get it under water when I build my next pc to see how far it will really go.

Don't forget your snorkel! :D

water cooling makes you feel like a pro until its time to move your pc and you have to spend an hour draining a loop that you made look nice but not super great at draining.

Thanks for the advice guys. :)
