CPU temp significantly lower in BIOS than on OS
Last response: in Overclocking
Hi there. I recently upgraded from a Cooler Master Hyper 212 to a Corsair H50.
Here are the changes in temps:
Idle in BIOS
27c(CM212)/19c(H50)
However when my system is loaded using Real Temp, I am averaging around 37c on both the CM212 and the H50 (33low/52high). Now this is understandable for the CM212 since the difference is not much but for the H50, it is a big difference between the BIOS temp and the temp with Windows 7 loaded.
The two questions I have are
Why is there such a big difference in temperatures in the BIOS and on Windows 7 with the H50?
Why didn't my temperatures drop after upgrading to the H50 from the 212?

No, they are about the same. But if you get two 2000+ RPM fans and put them in push pull and pull cooler room air into the case, the H50 will beat the 212 with the same fans by a teeny bit.
The H50 isn't real watercooling.
Maybe the 212 is better than the H50 at idle, but who cares about idle temps? Who checks bios temps except the first 20 seconds of your first boot when building a PC?
