Zalman 9900 question...

post #1 of 9
Thread Starter 
I am about to order a Zalman 9900, here the scoop. My lowest estimate for the about of height space I have for a CPU cooler is 152.4mm without having to remove any existing case fans. The Zalman is 152mm biggrin.gif My question is this, if I need literally a millimeter or less to get this to fit, will it hurt anything if I carefully remove a bit of the heatsink material via sanding/dremel etc? I'm thinking a dremel tool might cause a bit of vibration that could potentially damage something, so I will probably do this by hand, if necessary.

To abbreviate, will it hurt the cooler if I sand it a tiny bit to get it to fit, or is it too risky, if so, I'll just remove the side fan. Thanks!

I would highly recommend against doing any sanding on your cooler.
Some people do lap their cooler to provide a smooth surface, but it's not an easy task.
Purchasing a slimmer fan or removing the side fan is a much better and safer idea.
What case are you using?

I have the Raidmax Smilodon. I've has the case for 3+ years but just built a new machine in it. The new motherboard CPU socket seems lower than my old mother board's was. The lower case fan has some "graphics card stabilizers" that don't even touch the video card so I might just cut them off. My estimate of 152.4 I think is conservative. I think it will fit fine.

To be honest only Zalman CNPS9900 MAX is worth looking if the price is right.

To your question, why not look for blow down CPU cooler? Something like Noctua NH-L12 or NH-C12P? Slicing/sanding off a layer of heatsink is ill-advised.

Just fyi, the zalman 9900 the front set of fins/heatpipe are super soft and bendable, as are the fins...I would slightly bend fins before I started grinding on it.

As long as you are not cutting the heatpipes open, and you take off as little as possible I dont see an issue. I'm assuming youre shaving off a bit of the fins at the top?

Something else to think about: If the fan is not sitting directly centered over the cooler, try to set it up so it is blowing air onto the cooler in the same direction that the fan is spinning. That only works if they are offset, though, not if its just blowing over the entire cooler. Marginal benefits as the fan doesnt have to fight the air coming against it, but if its just a positioning thing, why not?

Just found the Max for the same price I paid for the 9900 NT, was able to cancel the order and get the MAX, thanks! biggrin.gif Only problem is it's not green but I really don't care biggrin.gif

Exactly, just a little of the top.

If you look around you might find someone who sells replacement fans. I had a bunch of zalman 8700/9500/9700 and I just bought fans and swapped them from blue to green. It used to be sharkacomputers.com but they are long closed, I would just email zalman and ask them where you can pick up parts for your cooler that is out of warranty.
