Corsair H40 Asetek Pump Tear Down, Interesting findings...

post #1 of 7
Thread Starter 
So recently I bought 2 Corsait H40's to use in my PC. Both showed up making horrible grinding noises. I sold the better of the two and tore down the other, here is what I found.

The first thing I saw was a bunch or gunk in the fins on the block its self:

That the heck is that crap? Why is it in my pump? Next I pulled it apart more and found some other interesting stuff. Here is the bottom of the pump, you can see the intake hole and the hole where the water is sucked in by the pump and taken to the RAD.

When the bottom is removed you can see the blades on the pump and a block of foam?

I am not sure what the foam is for, but the only way water gets to it is through the small cut out that faces the opposite direction of the flow of water. There is also a hole that goes all the way through the top and into the small open area next to the cut out and foam. This looks like it could be a air bleeding hole, but it is plugged with a screw and serves no purpose. Take a look at how the pump blades are mounted. No bearings, not even a metal shaft, plastic on plastic with rubber tips on both sides.

Whats more is that there is not the correct amount of spacing between the blades and plastic housing that causes the blades to rub and create the dreaded grinding noise. Asetek really needs to step it up...

I got an AIO a long time ago, and after running it for about a year, I took it apart and found that crap in my waterblock as well.

I'd like to know if anyone else knew what it was? Minerals from the water/metals?

Considering I bought this less than a month ago, I really don't think they have been fixed... rolleyes.gif
