[CPU] Healthy Temp for an i5 760 OC

Hi Guys,

Was curious about the temperature for my CPU. It averages at around 57 to 60 degrees Celsius with a normal load. I have used the asus auto tuner to OC it from the 2.80 Ghz to 3.66 Ghz average.

The scary part is when I tested it with Prime95 for all 4 cores, the temp shoots up to 100d C.

So the question is, should I be worried with the temperature and what is the average I should be getting? Did I mess up the thermal paste and cooler part or is it simply due to the OC from 2.8 to 3.6?

My Rig:
CPU: Intel i5 760
cooler: Tuniq 120 Extreme Tower
MOBO: Asus P7P55D
PSU: Corsair TX850
GPU: Asus ENGTX460 Top 1GB
RAM: G.Skill Ripjaws 12800CL7D 2X2GB
HDD: Samsung Spinpoint F3 500GB
ODD: Asus DRW-24B1ST

    1) You load temps are not safe and show you don't have adequate cooling.

    2) You should be seeing load temps in the mid to low 60's max with that cooler and idle's in the 30's (based on normal type ambient temps)

    I would highly recommend checking your heat sink application! 1) Make sure it is fully seated on the CPU & 2) Look to remove the HSF, clean off the thermal compound (CPU & HSF), re-apply compound and re-attach the HSF (confirm again fully seated). Afterwards, check temps again at idle and load with Prime95.
  2. Cool. Any idea where I can find a proper guide to applying that paste? It took me couple of hrs just to pull it through, not a good job too.
  3. It's not possible for us to say for sure, because we don't know what settings you are using in your OC. But, yeah, its highly likely its due to the OC.

    Of course, its possible you didn't attach the HSF correctly, but before you disassemble, you want to run Prime95 at stock sppeds. If temps remain reasonable, your HSF installation is probably fine.
  4. Okay. So I've reapplied my TIM but just a little now, I think i overdid it previously. So with the OC speed of around 3.6 ghz, it ideals at around 50. With the prime95 full load running, its around 78. That a sound figure?

    Here's a runthrough of my system from cpu-z:

    Funny thing are my rams. I've got the g.skill ripjaw F3-12800CL7D-4GBRM but why is it rated as 10700?
  5. 1) Those temps are better but still a little high. They should drop a little over time as the AS5 takes time to set in fully.

    2) Did you set your memory in the BIOS to the memory's specifications? If not, this is why since it is running a default / lower speeds.
  6. Oh I'm actually using the TX-3. Hm, should I use AS5? I have changed the timing for the rams in BIOS and the rated frequency is ddr3-1755Mhz (which I suppose had been OCed a lil). But the Max Bandwidth still shows PC3-10700 (667 MHz). Hm..
  7. No TX3 is fine... I just thought you said AS5 earlier in the thread :)

    I'm not sure why the PC3-10700 is there but it shows you running at the DDR3 1725 speeds, so I wouldn't worry.
