Loose VRM Heatsink On My 990FXA-UD3

post #1 of 7
Thread Starter 
Is it ok for it be loose? I was rebuilding my rig after I put some new fans in and while I was connecting the CPU connector, I accidentally used a bit of extra force and nudged my hand on the heatsink. The screws (or caps, those thingy's that hold it down with a spring on each side) don't feel too strong as I can wiggle the heatsink from side to side. But if I don't do anything, it stays in its natural position on top of the VRM's. I hope I'm making sense. I'll take pictures when I get home from school.

are those the white plastic push-pins? I'd say as long as it has sufficient pressure to stay on top of the mosfets your good. Maybe press down on it a little to help imprint the fets into the thermal pad.

Yup, those little white things. I did give it a good push and could hear the pads compressing. I'm just worried. I mean, my cpu heatsink has pounds of pressure on it so I would think the same thing would be happening with the motherboard's heatsinks.

Vrm heatsinks are normally not super tight, and can be wiggled left to right because of the springs.

OK, just making sure. Thanks smile.gif

Push the heatsink down, maybe put a washer on the bottom underneath the push pin for some extra pressure. I actually knocked the heatsink contact loose from the VRMs when I first got my boards, but proper pushing down was able to solve that - my VRMs load at around 50C. Very cool.

Yes as others have said it's normal to be able to wiggle the 'push pin' type heatsink. I've had that board too and you may have noticed that it came with a piece of foam wedged between the sink and rear inputs supposedly to hold it in place during shipping.
That little piece of foam did more to mis-align and 'loosen' the sink than I could ever had done.
For what it's worth the heatsink/thermal pad lift right off, you just have to compress the push pins from the rear. You can then adjust the pad and re-seat the sink if you want to.
