The part of the CPU cooling system that connects to the CPU is making awful noise:



The fan and radiator are not making noise and appear to be operating as intended. The cooling tubes are cooling. I disconnected the unit to get a better look and the back looks like this:



and the CPU now looks like this:



Anybody know what's going on here?http://www.diychatroom.com//www.pinterest.com/pin/create/extension/

That is way too much thermal paste. Along with the fact that whoever installed it, did not remove whatever old paste was on the CPU. I would clean all of it off and use Arctic Silver. You really only need a very small amount that is spread across the CPU. http://www.arcticsilver.com/# Also you have a lot of dust in there that needs to be cleaned out.

There's also green corrosion on the copper backing of the pump. Does that indicate a leak? Joed, the sound is coming from inside the pump, not any of the fans. This is what I found surprising in the first place.

What is the best way to remove the excess thermal paste?

The pump will have a motor in it. If it is noisy, then the pump must have a bearing going bad. If it is critical I would get another one on order as I suspect this one is about to die.

That Patina is the Thermal paste getting contaminated. I would order a whole new thermal kit from Newegg.com Toss the old one. You can also order the Silver Solder Cleaner and Silver Solder from them.

If you take it to a local shop with the new supplies, they should back it up with their warranty for the work if something goes wrong. Plus they can give it a good cleaning and testing for any hardware issues.

Definitely sounds like your pump in going. If that is a closed loop cooler it can be easier and more cost effective the replace the entire unit. Corsair units have a thermal compound on them that is already a good mid-range product. No need to use a third party one unless you want and even better compound. AS5 is not any better than the stock compound. AS5 is still an okay compound but it's old tech now. Look at Gelid GC-Extreme for a very good moderately priced compound. Definitely clean that junk off. I use the Arctic cleaning compound and purifier I've had for years and coffee filters to remove the residue after scraping excess off with an old credit card. The Gelid compound should come with a spreader to evenly coat the new block.

I ended up replacing it with the ARCTIC Freezer 7 Pro which barely fit, but is less expensive and works really well in that PC and came with the thermal paste already applied. As per the advice of some other friends, I cleaned the old gunk out with an alcohol swab first. The computer runs really well now and is quiet.
