Hi all.
I'm fed up with the sound of my budget CPU cooler.
I'm running a AMD Athlon 1800+ (not overclocked) and I'm wanting a cheap (sub $40-50) HSF.

I've seen those VOLCANO fans - and they're in the right price range (the VOLCANO 8,9,10 all are less than $50) are they low noise fans? or are they more aimed towards overclocking? - which i don't need

Some other ones are:
TR2-M2 CPU COOLER
TR2-M4 CPU COOLER
TR2TT M1 CM &AMD
TR2TT M3 CM&AMD3400
and the Volcano 8, 9 and 10

Thanks

Apparently the Volcano series while being very good at cooling they sound like a rocket engine.

Is a good place to start from.

putting "quiet Athlon fan" in Google is helpful.

Thing is most people on F1 haven't done multiple tests on these fans, so we tend to rely on "expert" comparisons

Cheers
And thanks for the link!

How quiet do you want it. For eg, I don't call 38dBA quiet. 19-22dBA is quiet.

The most successful way to get your CPU HSF noise down will staying relatively conventional is to increase the efficiency of the heatsink that allows a fan that does not need to push as much air (CFM). At the same time if the setup has a larger fan (80-90mm rather than 60mm) you can spin it at 1200-2200 rpm rather that the 3500-5500 the smaller higher speed fans need to spin faster to push enough air to provide the required cooling. High fan speed = noisy machine.

Unfortunately high quality efficient heatsinks are not the cheapest heatsinks. Generally the pure copper are better than aluminium or copper aluminium mixes. The Zalman CNP flower coolers do the job very well but they cost a lot more than $50- although every now and again (2 or 3 times this year) PC Gear have specials on them in your range. You can check them out and others at Quiet (http://www.quietpc.com/nz/), Over Clockers NZ also sell them (OCNZ.co.nz I think).

Check out Silent PC Review (http://www.silentpcreview.com/) for good info + a comparison of various fans and heatsinks for CFM & dBA output.

Nope. THG is grain-of-salt material.

are infinately more useful.

It's been mentioned already, but do check out the Zalman gear.

Just a little bit of advice. Make sure it is the CPU fan, I thought mine was noisy. It turned out to be the video card fan. I have a very technical testing program for problems such as this. I stick my finger in the fan for a couple of seconds. You'll be surprised where the noises are coming from.

"How quiet do you want it. For eg, I don't call 38dBA quiet. 19-22dBA is quiet. "

Some of the claimed levels are VERY optimistic. Cheap meters aren't accurate below 40dBA.

"30 dBA Sound Pressure Level is the sound level of a quiet room, with all doors and windows closed, and no ventilation systems on. We characterize it as "extremely quiet." A normal classroom at Berklee, during the day but when nothing is happening in that room, has a Sound Pressure Level of between 35 and 45 decibels."

The standard AMD heatsink from a late model Barton is quiet. Perhaps someone that has bought another HS could give you one.

Will second this one, but be VERY carefull stoping your CPU fan!!!!

Just replaced the fan on my GEFORCE4 card and well over half of the PC noise has been eleminated!!

Yep, my chipset fan is the loudest thing for me (although regular doses of CRC keep it bareable).

As was mentioned above, the volcano fans are insanely loud, but the base isn't too bad (for the price) and it fits 80mm fans.

I run the heatsink from a Volcano 11 with a cheap-but-quiet DSE fan (2000rpm, 20cfm, 20dba, blue leds :-)) and it keeps my athlon 2100 cooler than the standard HSF.

Stick your finger in a volcano and youll have something technical to worry about alright.....
