Extreme Temperatures

post #1 of 27
Thread Starter 
I have recently been trying to overclock my machine and it has been a bit of an issue.

OCCT thinks that my CPU temp hits 72c under load, yet speedfan thinks that core 1 hits 45c and core 2 hits 60.

Obviously i have a cooling issue somewhere but is it normal for several different programs to all show different temps??

Surely they all read it from the same place, I have an LCD poster that tells me the CPU temp and that thinks it never gets above 40c

I would try reseating the heatsink, also make sure you have good thermal paste. And no matter what anyone tells you about how to apply thermal paste every cpu/heatsink is different and needs its own amount. You may have to test a bit to get temps right. Also make sure you have enough case airflow. The other thing is the 6400 is a hot running cpu.

Thanks, I used the thermal paste that came with the heatsink so its probably not up to the job, is there anything you would recommend?

I have 1 120mm side fan and a 120mm rear fan aswell as the CPU fan. Will I need more?

I have been thinking about going for liquid cooling

Artic Silver 5 is the gold standard of easy to use, it does require a bit of break in before you get full benefit though.

Other good choices:
Shin Etsu - super hard to get right
OCZ freeze - supposed to be easier than AS5

I have an air cooled system and under load OCCT says CPU too hot even though its limit is et to 80c

Speedfan claims that the cores never go above 60c

Surely this is still hot, I have a thermaltake blueorb heatsink, and a side mounted 120mm case fan aswell as a rear 120mm case fan.

Do i need more fans?

Are the temps wrong?

Didn't we already discuss this?

http://www.overclock.net/amd-cpus/331132-occt.html

Anyways, what case are you running? What fans do you have and what are they doing? I take it you still don't want to use coretemp?

And as I mentioned in the last thread the 6400 runs hot.

I have just downloaded coretemp, will check the temps under load

I have a nxzt case, 1x120mm fan on the side mounted pretty much in line with the CPU and a rear 120mm fan.
