Radiator creating horrible vibrations against case

Goose · 15 Jul 2015 at 18:13

I installed a Raijintek AIO cooler to my 750D a couple of weeks ago and once or twice a day I hear a really horrible buzzing sound coming from it caused by the radiator mounted to the top of the case. I think the screws I used (the ones that came with the AIO) are to blame as I could never quite get them all screwed in tight. I think the rubber grommets might actually be a problem too as they get in the way of tightening down the screw. I've included a (crappy) picture in case you're interested.

My question really is what type of screw should I buy to firmly mount the radiator to the case?

Thanks

You could try getting some anti vibration mount screws, it'll make your rad not sit flush to your case.

Thanks for the advice but i cant really find anything that looks like it will be universally compatible with all radiators and cases.

what like 8 rubber washers, universally compatible with anything requiring a hole in it

This. Halfords, b&q all sell little rubber o rings, just put them between the rad and case

Ok then, thanks for the sarcasm. I assumed the first guy was talking about some sort of radiator mounting kit, how stupid of me.

Dunno your cooler but it seems odd to have rubber washers between the screw and the case, this will do nothing and it will be the fans causing the vibration not the rad, what speed are the fans running ? try reducing the speed if it seems to high.

Get some metal washers to go between the case screws and case, and some rubber ones as suggested between the case and rad, it's an easy fix.

Sorry Goose, just made me chuckle, but this is why questions are asked in forums.
100+ people have looked at your problem, most will have seen that someone had advised an anti-vibration kit, which unfortunately are not always compatible, then closed the thread thinking nothing more of it.

Sometimes the most simple solutions are overlooked

Even simpler - cut an elastic band and place it between your fan and rad. Simply screw threw the laccy band and jobs a good un - it'll provide some further absorption for vibes

cheap yet cheerful and effective.

The rubber washers are from the case rather than the cooler. All fan/rad mounting holes in corsair cases (afaik) use these rubber grommets for anti-vibration purposes. Which is ironic given that they might actually be the problem.

I haven't yet been able to decipher if the vibration is radiator/case or radiator/fans.

I'd take the rubber washers off and use metal ones, but you just need to push against the rad and see if the noise stops, should be easy enough to figure out.
