CPU Temperature Overheat

Hey guys.

So I installed a new cooler today (Cooler Master liquid cooler, Seidon 120V Ver.2) - I finished installing it (complete with fresh new thermal paste, cleaned it properly and everything). I turned it on (moment of truth) and my BIOS just kept beeping at me and said "CPU Temperature Overheat". I went into the Temperature Monitor tab in my BIOS and it says 100+°C!

So I put my hand over the pump, no heat. I put my fingers around the socket, no heat. I check the temperature of the North and South bridges, no heat. It's all cold. Cool. So why is my BIOS falsely reading over heat detections?? Would this occur because I took off the BIOS jumper whilst my PC was off? I don't know.

Could you awesome people give me any suggestions?

Thanks!

Something very very similar to this happened to me when I first was building my PC. My CPU was said to have been running at a decently high temperature, so I got a new fan. And guess what... It was a CoolerMaster, just like yours!

Anyways, here is all of the help I can offer:
*Make sure you always use the pea drop method when applying thermal paste, spreading is no good. If you did not do so, I urge you to reinstall the fan with this method.
*Just read an article by someone having a similar problem, and one response said to reset the BIOS (clearing the CMOS and updating the BIOS if possible)
*One of your pieces of hardware or the CPU itself may be defective, maybe try booting up with just one stick of RAM in.
*Make sure the fan on the front of your build is sucking in air, and the one in the back is blowing it out (to make sure you have proper air circulation).
*Check your fan spinning rates in the BIOS, are they not spinning at optimal rates?

That's all I can think of man. I wish you the best of luck though, try some of those procedure out and let me know what happens. :)

I'm not sure whether or not it's doing this because of this cooler or I accidentally removed the BIOS jumper. Of course since it's happened to you, and many others, it kind of proves the liquid cooler product itself is bad.

I read through your post and what you mentioned to try, I've already done. I'm not sure what to do. Whether I should get a different cooler or not.

I can't boot into Windows. It won't proceed further from the POST because it's detecting a CPU temperature over heat. It just asks me to reconfigure my system.

Are you sure you installed it correctly?

Hi,
Go to bios and Optimize defaults and save and exit :/

In the BIOS it shows CPU Vcore at 1.5v for some odd reason. It only started doing this when I removed the BIOS jumper plug from the 2 pins it's on. The CPU Temp in Temperature Monitor shows 127C straight away, which means the CPU isn't really overheating because it wouldn't have enough time to heat up that quick. It was only on for 1 minute or less.

I installed it correctly and checked everything 5 times. The fan on the radiator works, the pump block lights up blue, I can feel water pumping through the pipes. If it was really overheating, the CPU pump block would be warm or hot and the radiator would be hot as well. (right?)

It just seems like the BIOS settings and CPU vcore voltage is messed up as it should never be at 1.5v on AUTO.

Hi,
Silly question but is the heat sink making contact with the cpu :/

Did you remove the cpu ?

I'm not understanding the jumpers stuff ?

The pump block is making contact with the CPU.

A jumper basically clears the CMOS. It's like a CMOS clear switch/button but a better method. It is 1 of 3 ways to clear the CMOS.
