CPU Fans - highly variable quality.

Well, I tend a rather large herd of Dell Optiplexes (amongst my other duties), and we've got some rather ancient examples (P2 300, bought mid-98) and they have Intel slot 1 processors - as packaged by Intel. Intel fit high-quality Sanyo fans to their processors, and they're damn good. We've had just about every other thing fail on these boxes, but I've never had to replace a processor fan.

A quieter power supply probably wouldn't go astray, but it's the CPU Fan that is the most noticeable. THe fan on the graphics card is hardly noticeable. Apart from all the red 'panic! panic!' messages the fan-watching software puts up :) Other results: Cotton Bud (Qtip) is now rather dirty. :) Plans: Maybe get new CPU fan - and maybe buy another hard drive so I consolidate stuff from two drives onto one. On and on and on and on, and on and on and on goes John.

You might not be able to do this since you have a Duron, but I made my server a lot quieter by replacing the heatsink+fan combination with just a heatsink. Mind you, my server runs a Pentium 100. :-) And it took me many months before I found a Pentium with only a heatsink. Perhaps you could rummage in Google for [link\|http://www.google.com/search?hl=en&lr=&ie=utf-8&oe=utf-8&q=fanless+CPU+heatsink&spell=1\|heatsinks without fans]. Like [link\|http://www.pcstats.com/articleview.cfm?articleid=627&page=3\|this], perhaps? Wade. P.S.: I just found [link\|http://boozhoundlabs.com/bigsink/\|this]!

Post #39,582 by Meerkat 5/22/02 11:47:33 PM Reply	I ned some WD40 - ta for the reminder! It's first use will be on the wheels of my garbage bin. Curently sounds like a chorus of chirpy birds every time I take out the recycling. But hey, it's worth a look to see if I could squirt some onto the fan workings without damaging anything. Yes, I will ensure it's well away from the CPU at the time :) On and on and on and on, and on and on and on goes John.

Axial chatter (shaft bouncing off the end stop), or ball race chatter, or shaft chatter (if it's a sleeve job). More lube will make it chatter better. [link\|http://www.aaxnet.com\|AAx]

It's only redeeming value is that it is better than air between your CPU and your heatsink. If you want a heatsink to absorb heat, you need a large mass of metal with decent thermal capacity. Hence the weight. If you want a heatsink to radiate absorbed heat (e.g. for fan cooling :-), you need a lot of surface area. Hence the finned designs. Wade. My physics in this area is rusty, but IIRC this is why water-cooling works so well. "All around me are nothing but fakes Come with me on the biggest fake of all!"
