Cpu Cooler Fan Replacement?

post #1 of 8
Thread Starter 
Hello,

I own a CoolerMaster Hyper212+ cpu cooler with a blademaster 120mm fan, and as most of you know, the stock fan has a sleeve bearing. I have owned it for just a little over 10 months now. It has preformed well up until now.

About a month ago. I changed out my old case for a new Silverstone Raven. Which flips the motherboard 90 deg. Causing the cooler to switch to a horizontal mounting position. I've read that sleeve bearing fans don't like being mounted this way. These past few days the fan on the cooler has started making some rattling and buzzing noises. I can almost make the noise stop if I apply some pressure to the fan and the heat sink, almost making my fingers act as vibration dampeners. I'm not sure if it's the fan bearing, or if it's vibrating on something. I'm guessing it's the bearing since everything is sturdily mounted, including the fan to the cooler.

I'm wondering if I should try to re-oil the fan to see if it fixes it. Another option might be to RMA the fan if it is going bad. I think I have about two months of warranty left on it. Or just buy a new fan without a sleeve bearing.

Thanks in advance for any input.

when you change the orientation of the fan, it usually changes the RPM it spins at ever so slightly. it could be that it's hitting some kind of harmonic frequency that causes it to vibrate. you can try to RMA the fan, but not sure if it's worth the trouble and down time. what i would recommend is to replace the cpu fan with the case fan that came with your raven(the top case fan of the raven is a 120mm) and see how that works out for you. case fans aren't the best cpu fans, but unless you are doing some heavy OC, it wouldn't matter anyway.

Thanks for the advice.

If I do choose to buy a new fan. What would be some good recommendations? I would like to get one with a low DB level. I'm not really looking to go into a push/pull config either. I've been happy with my temps with just the single fan.

I was thinking of maybe getting a Noctua fan. I've always heard good things about them. They are just a bit pricey side though. Would one of them preform adequately with a 212+ cooler?

if you are using a heat sink, try not to use GT-AP, it has a big fan motor which means it provide good static pleasure BUT that also means a big dead spot..

I would personally recommend 2nd hand noctua p12 fans, they are good for heat sink.

Supposedly these have rifle bearings. Can't find it right now.

Take the fan out. Look at my sig for a link to re-lubing your fan. If you can get to the bearing, it's a sleeve bearing.
