Seidon 120V CPU Temp Overheat

Recommended Posts

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.

 

CPU: AMD Phenom II X6

Mobo: ASUS Crosshair IV Formula AM3

 

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.

 

NOTE: I CANNOT boot into Windows. I cannot get past the BIOS POST as it just says "CPU Temperature overheat". Even though I feel absolutely no heat coming from the CPU block/socket/CPU or the radiator. There is NO heat coming from anything yet BIOS reports overheat at 127°C.

 

Could it be reading my CPU surface temperature and not the core?

 

Could you awesome people give me any suggestions?

Thanks!

Hey

 

Welcome to CM forum,

 

1, try Disconnected your Seidon and try reseat or Repump the Seidon and see How the result

 

2, Try tighten the screws by hand as much as you can and then give them 1/4 to 1/2 of a turn with a screwdriver.  ( dont over )

 

3, If you start up the cooler, you should feel the pump working // running. (if you touch the tubes or the cpu block, you should fee a small vibration, indicating there is a water flow.The pump RPM should be around 2100-2300++  RPM btw., 

 

4, Could be air (bubbles) trapped in the radiator / loop. Eventually this will disappear.

 

5, RMA your unit

 

6, Last step , If you're really concerned, I would recommend contacting support services via email // ticket // live chat and seeing what they say about it-- they should be able to tell you more definitively.

 

 

Try step 1 2 3 and no 6 for sure :)

 

and try check FAQ as below

Hope this can help

It also sounds like if you're immediately getting the temp overheat shutdown right after turning it on - it's a sensor or BIOS issue.  You should have some time to at least enter the BIOS screen while the CPU heats up.  I recall inadvertently powering up an old AMD Athlon chip without a heatsink while the motherboard was on an open test bed and I know took at least a minute for the BIOS to register something was wrong.

 

Do you have a easy to install stock cooler available?  You can mount that temporarily onto the CPU (without paste even) and see if you can get into the BIOS screen - go to Computer Health and see what registers.  If you can't get past powering on the motherboard - issue is most likely the mobo or sensor.

 

Have you reset the CMOS?
