better fan for coolermaster

[seeker]

Anyone know of a site that's done testing and/or have personal experience with different fans for the coolermaster? Muchas Grass and Merry Christmas to all:)

Any fan that flows more than the cooler master stock fan will lower your temps. But the heatsink is the most important part of the two. The coolermasters I've found, just don't cut the mustard.

Get the Delta 60mm 38cfm and you'll notice lots of changes in the temperatures.

I've got a Coolmaster on my K6-2, and higher cfm fans (30cfm, 40 cfm) didn't lower temps and were loud, though even with a wimpy fan its good enough for a K6-2 (especially after lapping).

Some of the fans that come with these heatsinks are really sorry, though, and replacing with a decent 60mm x 25mm will help lower temps.

If your trying to cool an Athlon with one, replace the heatsink while you're at it.

I used to think highly of coolermaster, having some 486 and pentium classic hsfs from them in service for 5 years or more and being able to overclock pretty well under them. Then I got a couple for super 7 CPUs, and although on the large side, their cooling ability is only average and the fans started rattling after only a month or so despite being "ball bearing" units. Mind you, fans never seem to live long in my climate, I end up oiling them all every few months.

The heatsinks in these later ones may be a factor, since I get better results on on K6-2 I have from a very cheap heatsink with a coolermaster fan on it. It originally got on there when I had the hsf stuck to a 6x86 and the fan died, and I bought one of the coolermasters and changed the fan over. I later cracked it off the 6x86. The sink is lighter than the coolermaster one, but has far more crosscuts, thinner fins, and is slightly taller. The cooler master ones I have seem to have too much metal in for their cooling area. Some people like more of a thermal buffer, but it tends to deceive you when setting up a system, the sink will soak up heat for 30 mins and all will seem fine, then your system will crash, I prefer more area with less bulk, so it crashes sooner rather than later, if it's going to, so it's easier to figure out "where you are" when trying overclocks.

So, changing either the sink or the fan might show improvements, since IMHO latterday coolermasters are badly matched. But for all the hassles you may as well just replace the whole thing. Socket A and S370 celeron coolers on K6-2s are NICE, even the cheap ones.
