Help with high temperatures with h105

[aragur]

I just replaced my motherboard and cpu cooler in my computer yesterday.  I got the corsair h105 in hopes of lowering my cpu temps but instead, I got the opposite!  My computer is running a lot hotter than it should (in BIOS my temps stay around 83°C) and I cannot figure out what is the matter. My specs are:

• Motherboard: ASRock z77 Extreme4
• CPU: Intel i5 2320
• Cooler: Corsair H105
• Case: Fractal Design Define R4

I have googled just about everything I can think of to come up with an answer but nothing seems to work. So I am completely out of ideas.  If you guys have any advice, I would greatly appreciate it.

Something is definitely not right. Since that temp is extremely high, first thing I would check is your pump. Find out if the pump is running properly. You have it connected to one of the fan header right? check the pump's rpm and see if its around 1700rpm range. Make sure its getting 12v all the time from that fan header. I would also check the contact between your CPU and cooler's cold plate, make sure it is properly seated with no play or what so ever. Poor contact between the CPU and coldplate can cause your CPU temp to skyrocket in a few seconds.

That shouldnt happen on a non-K sku.

 

Check pump, fans and thermal paste

I have the pump connected to the CPU_FAN2 header on my motherboard with the rad fans connected to the CPU_FAN1 header.  The rad fans are running at about 2575 rpm, but my BIOS is listing the CPU fan 2 speed as N/A.  Does this mean the motherboard is somehow not controlling/sensing the pump?

 

I checked the thermal paste as well and that seems to be fine, and there is no play where it is mounted to the cpu.

That will most probably mean ur pump is dead.... Can you hear the pump, like at all?

The corsair logo lights up when I turn the power on, but I do not hear any significant noise coming from it.

Sounds like a dead pump to me.

Pull out the fans, and put the pump in pwm1.

Set pwm1 to full power. If no pwm signal nor any sound from the pump at all put the pc off and rma that h105.

All aio pumps make atleast a little sound. If it is not audible at all its not working. Stick your ear next to it if you have to

----Edit----

You can also feel the pump work if you put your finger on it.

Btw if you have any way of delivering power without turning the pc on that would be preferable

I switched the pump power cable around to about 3 different headers on my motherboard and even unplugged as many other fans as I could and still all I could hear was the hard drive.  I think you guys are right and I ended up with a dead pump.  Thanks for all of your help guys!  I am not sure if I could have figured that out on my own.
