hello guys

recently built my computer and got it working but theres a problem

i have the i5 sandybridge 2500k on the asus sabertooth p67 rev3 motherboard

when i load up i get an alert that the cpu temp is to hot

i go into the motherboard to look at the temp and it starts at 80 then rises to 97 C and stays on that

i have 5 fans in my case 2x 120 mm on top of case

2x 120mm on the front of case

1x 230 mm fan on the side

the cpu fan is apparently running at 1950 rpm ish per minute (the cpu fan is the intel standard which comes with the cpu)

i have a lot of fans in the case and the cpu is running very fast but yet the temp is really high

so i expect it to be very cool

is the motherboard detecting it wrong? or is it a fualty fan but i cant see why running at that speed it would be that high

also were the fan is at 97 C youd expect to feel abit of heat coming of it when switched off but you cant feel any heat
 
Have you made sure the heatsink is installed correctly? If it was me with this problem the first thing I would do is take off the cpu heatsink, clean off the thermal paste and reapply some decent thermal paste according to the instructions, making sure everything is fitted correctly.
 
If the CPU is at that temperature, and there's no heat coming off the cooler, then the cooler can't be making proper (or any) contact with the CPU.

The heat is not being transferred from the CPU to the cooler.
 
Just on the CPU itself, if you are using a paste, and you only need a small amount.
Here is the instructions for Arctic Silver thermal paste on Intel cpu's, it's good stuff and it's what I use although there are lots of others to choose, just try to find instructions as it may be different.
Don't forget to clean off the old stuff first though.
