Problem I'm facing with CPU and all in one water cooler (worried about fused thermal paste)

gonepostl 4,100 338 December 30, 2015 at 11:35 PM
So, I have to return my motherboard and cpu. My temps are insanely high for a cpu that has a liquid cooler, 90c full load using prime95 (i7-4770k). I have a feeling that the cpu is stuck to the heatsink on the all in one cooler.

Here's the problem, I can't access the latch to release the cpu from the socket. I'm worried that if I pull the heat sink block from the AIO liquid cooler that it's gonna F up my cpu pins. So what the hell do I do?

Here's a pic of what I'm talking about. I can't access the latch without pulling the block off:

Why do you think the CPU is stuck to the water block?

What kind of thermal paste did you put on?

Did you build the system?

The solution is to drain the water system, and unassemble the water block. I assume there is a bracket on the back of the motherboard that the top screws into. I know most coolers air or water use extreme pressure to ensure they make good contact. The Pins are on the motherboard not the CPU on your chip. Internet seems to suggest a bit of twist action. http://www.sevenforums.com/hardwa...u-fan.html

Sure you have proper contact to the CPU, no air in the water loop, your pump is working, and your radiator isn't blocked/corroded?

What pins

Unlock the cooler and give it a slight twist left and right

I haven't seen any system that you need to unlatch the CPU before taking off the heatsink - what would the CPU be stuck to, the heatsink with some weak thermal compound? much safer to have it locked in until your ready to take out just the CPU itself (and all the goopy mess is cleaned up)

Ya I built this system 2 years ago. What's the point of the latch on the cpu socket?

The reason I think it's crusted is just because of the insanely high cpu load temperatures and how hard I've been using it for years. I can't afford to ruin this processor.

No, Just disassemble it like normal. The cooler won't be permanently glued to the CPU. It might need some tapping but will come off.

The latch on the CPU socket just basically retains it electrically. Its designed to withstand the force of the cpu coolers. Not even going to go into the temp/troubleshooting routine here.

Most likely that either the pump in the cooler is not working properly, or the liquid has grown algae and is barely moving through the cooling system. Why do you think that the motherboard and/or CPU need to be returned?

Nothing is wrong with the pump from what I know, I just want a new cpu/mobo is all. It's a closed loop AIO cooler, I couldn't drain it if I wanted to :-/

I have the same CPU, overclocked to 4.2 GHz and it stays around 60c running Prime95 using the In-Place FFT's "maximum heat" torture test. No water cooling, just a CoolerMaster 212 EVO. That's why I wonder what's wrong with your cooler, unless you're shooting for a super-OC with really high core voltages.

As for removing the pump, just unscrew the four hold-downs, slightly twist the pump and it should come right off. Only after it's out of the way can you undo the CPU latch. Even if you could get the latch undone before, you run the risk of damaging the CPU pins on the motherboard. Bend those and any MB warranty instantly becomes worthless. Frown

worried about bending the pins when I twist back and forth.

pull it up slowly without twisting, i had it couple times with old dell boxes, after 4-5 years the paste dries and turns almost like glue. after that i used screw driver to remove cpu.

If you look at your CPU, you don't have pins. They haven't had pins for sometime now.
You place the CPU, flip the cover and lock it down. Unscrew the thing and see what happens

won't be an issue - the latch will keep the pins and the CPU stationary relative to each other, it's just sticky stuff on the flat metal top of the CPU and the flat metal bottom of the heatsink, i.e. two relatively tough surfaces

though I suppose if you are still worried, you could use some floss or something to cut through any resistance and make it easier for peace of mind

Thanks so much for your responses, everybody else too! I'll pry it apart very soon and reply back here when I'm done.

Pins are on the motherboard on this model of CPU anyways.
