i5-2500K Stock cooler temps

[legohorse]

Hey, been following anandtech for awhile now but just created a forum account as I've just assembled my first PC.

During the assembly, after placing the stock cooler on my i5, I actually removed it in order to take out the CPU to reset the CMOS and then replaced it. As such, I was concerned about the temps as I've read that after removing the cooler, it is advisable to reapply thermal paste, which I did not (didn't have one on hand anyway).

My mobo is Asus Maximus IV Gene-Z and using AIsuite II which came with the mobo, it reports CPU temp of 32C when idling. HWmonitor reports the cores to be on average idling at 42C. My room temperature is around 27-29C. When I torture tested it using Prime95, after 5 mins, AIsuite II reported temp of 85C, and still rising slowly (based on trend of the graph for the past 5 mins). HWmonitor reported each cores to be at approx. 94C. And I did not OC it, everything is as factory default. I did however, update the BIOS to 0902 which is the latest on ASUS site.

I'm not sure if it will affect temps, but my current rig does not have a graphics card yet and I am running windows using the integrated graphics provided by the CPU. Are the temperatures recorded too high or are they normal?

Thanks for any help rendered.

Hmm I was hitting 72 using stock cooler in IBT but that was after being overclocked to 4200 🙂

Then again I have it in Raven 2 and I replaced TIM with Zalman STG-2 from the start.

Anyway I'd say yours are way too high

And anyway you have expensive as hell mobo why didn't you get $30 after market cooler like Coolermaster 212 ?

My dad would disapprove haha. Ain't my money and he doesn't see the point of getting aftermarket cooler. I guess I'll try applying new thermal paste and see how it goes.

BTW, what does IBT stand for? And I assume Raven 2 is the model of your chassis? My chassis is Phantom 410.

Thanks for your reply!

same chip here, when im in Windows just messing around on the web etc my temps are around 27c-35c, each core varying a little.

playing crysis 2 or under heavy loads, it will max out around 60ish C.

yours sounds HOT HOT HOT

i think they are a little high, i have the same chip with the stock cooler not OC, running prime 95 i hit 73-74 degrees C and that was with an ambient temp similar to yours. You should make sure that the cooler is properly installed, that push pin setup on stock intel coolers is really easy to mess up

how is your airflow in the case?

IBT = IntelBurnTest, stressing program

I recently built another 2500k... in an SG02 mATX case, not the best airflow(PSU fan and cpu cooler fighting for airflow, stress @ stock clocks/turbo ~= 75C

it's probably best to replace the thermal paste, and use a 3rd party cooler anyways... i have a 212+ in my first build in my sig, stress at stock clocks ~= 55C... a 212+ usually sells < $30

So get him one for xmas and install it for him. Even a cheap aftermarket cooler will pounce the stock intel one. About the only thing the stock coolers are good for is test booting the system before you build the rig. 🙂

Ok so I went to get thermal paste. Bought MX-4 Arctic Cooling as recommended by many forummers. I think I got the fan down correctly as I pressed the 4 pins until I heard a click sound.

Anyway, thanks for all your replies. I'm checking temps tmr again when hopefully the thermal compound has had time to cure and to spread evenly over the contact surface.

Remember to pull lightly on the individual pins to check if it's securely locked into the socket. It's not uncommon to have a pin 'click' but still be halfway out of the socket. Just give a gentle tug onto the corners to make sure it's in.
