I bought brand new Core i7 2600 (socket 1155) CPU with box cooler on it. I assembled a minimum booting configuration and in the BIOS it shows steady 73-78 degrees CPU temperature right off the bat. It seems very high to me, considering that all the case fans are working and the case isn't even closed yet. The fan is working at 1800+ RPM. Motherboard temperature is at 26-27C.
Now, it's not my first build and I'm pretty sure that I didn't do anything idiotic. The radiator is well placed and doesn't move. Cooler is plugged in the CPU_FAN socket on motherboard. First I was using the termopaste that was attached to the radiator. Then I tried to apply the one I had in place, which worked great the last time I used it. With new termopaste things don't change, it still hovers just below 80 after few minutes of work in BIOS.
I'm aware that stock cooler are considered crap, but 75-80С idle seems ounreasonably high. Will good aftermarket cooler help or is it something wrong with the CPU itself? Does warranty apply in such cases?
