I decided to test the system before installing it in my CM 690, so I just installed the CPU and one memory module on the board on an open table and powered the system on. I was using my DeepCool GamerStorm CPU cooler and DeepCool Z9 thermal compound.
Since I don't have a hard drive installed or an OS setup, I was only using the EFI (BIOS), which shows the idle temperature at 47-50 °C for the CPU and around 33 °C for the system (motherboard). My room temperature is around 31 °C. I couldn't verify through CoreTemp or any other tool since I haven't even installed Windows yet.
I had the same cooler and thermal compound running on my AMD build which was overclocked to 3.5GHz at 1.45V and idled at around 26 °C and used to max out around 50-52 °C under full load, so I'm certain the cooler+compound combo is really good.
I plan to overclock the system and am expecting to go at least as high as 4.5GHz and I'm guessing these temperatures would certainly hinder that.
What are the average temperatures that are considered normal for a Core i5 2500k? And if there is really something up with my build, any guesses what I'm doing wrong?
Im running a 2600k OC 4.8 on Zulman CNPS10X Cpu cooler and getting 28 - 30c idle and prime 95 58 - 61 full load. Mind you i just bought a AC unit and now temp is down to 18c, when my room temp before AC was at 35c i had idle of 40 - 43 idle - 70 - 72 load. so Ambient temp does make temps vary!
