Hi there.
My mobo is a GA-Z68X-UD3R-B3, CPU; Intel 2600.
My temps as of now are;
Core 0, 39c
Core 1. 36c
Core 2. 37c
Core 3. 41c
Package 41c.
HDD 1 & 2 = 39c, 36c.
GPU, 36c
I rarely go over 45c, unless testing, your CPU should take 80c easily for hard work, short periods.
45c is pretty good for all round performance.
My room temperature is 30c, humidity is 55.
Do you have a stock fan on your CPU as mine is a "Noctua", (after market) I removed my stock fan.
Ben.
