Can I Rotate My Heatsink without Removal?

post #1 of 19
Thread Starter 
Shortly after Christmas I got the Hyper 212 EVO and mounted it so air goes bottom to top, rather than front to back. However, I wasn't aware that when sleeve-bearing fans are mounted horizontally, they make annoying clicking/grinding noises. Since I can't and won't shell out $34 for some FDB fans, I want to rotate my heatsink so it blows front to back. My question is if I can simply rotate the heatsink since I can rotate it without removing it, but I want to know if that is okay to do, or if I have to remove it, replace the paste, and put it back on.

Thanks

So it won't mess up the thermal paste or create air bubbles or anything?

No, you will need to reseat and repaste the heatsink..AFTER you clean off the old stuff.

Oh I was nervous enough replacing the paste when I switched heatsinks, so I guess I will leave it with the noise. Is there any way to reduce it? They are really new so would adding more lubricant help at all?

Assuming I get new fans in the future, would FDB fans be the best?

Also, I know people like the Scythe fans like this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16835185065

But this one has the same CFM but with 20 dBA less noise! http://www.newegg.com/Product/Product.aspx?Item=N82E16835226045

Which would be better?

EDIT: Also, it only seems to make noise when they are at their max speed, which I think they are at by default. Is there a program I can use to maybe slow them down a bit? Also, the noise is random. Sometimes when I start my PC there is almost no annoying noise, other times I can't stand it.

You could totally get away with it. I take off heatsinks without reapplying goop all the time. I'm not too concerned about 2c. I would just be weary of strain on the PCB/socket pins. my 212 actually slides around on my proc, doesn't bother me none. I still load at 42c.

If you're happy with your temps, just set your CPU fan in the BIOS to run at a happy medium of 1200 RPM's.

1500 is probably grinding point. 2k is probably grinding/take off point. Mine spins at 1.1k on full load. Only fan I can hear is my top 220m that's on full blast just cause I like putting bits of paper on it and watching them fly about. whistle.gif
