replacing fan on socket A Athlon 2400

[Strenge]

Greetings,

I'm wondering about possibly using a 60mm-to-80mm adapter and a quiet 80mm fan (Nexus, Panaflo etc) in place of the regular 60mm fan.
The adapter looks like: This


My goal is a quiet(er) pc. Far as I can tell, the main culprits are my case fans (Antec 630-something) and my cpu fan. I don't overclock, and many of the 'fancy' heatsink/fan combos I see would seem to be more for overclockers. A friend gave me a Zalman 7000A heatsink/fan, but my MSI mobo does not have the required mounting holes.

I was going to order several 80mm case fans anyway, so adding another with that adapter would be a cheap and easy way to quiet my machine a bit--IF it works. I've heard conflicting advice on this subject from the folk at silentpcreview.com, so I thought I'd get more opinions here. Some said it works, others questioned the cooling ability. Again, I don't overclock fwiw.

Thanks for any info.

IMO with a older 2400 as long as you have some air flow across the heatsink it should be fine. I dont see whay that adapter with a 80mm fan wouldnt help the temp's of the cpu.

Thanks for the reply.

As far as I know, temps aren't an issue with the 60mm, so as long as the status quo is preserved temp-wise, it's good. Hopefully the noise would be much less!

I actually saw an improvement in cpu temps by using an 80 mm fan on a stock AMD retail heat sink. It was on a Thunderbird 1.33, and that was a pretty hot-running cpu compared to yours. The fan was somewhat quieter, but the QUALITY of the sound was also less annoying -- the small fan had a whiney sound that is like fingernails on a blackboard or maybe like that TV actress puts on to sound like a New Jersey fishwife.

Nice avatar

I take it you used the same kind of adapter? If so, was it plastic like the one I linked?

I had a minor bit of uncertainty about using a plastic adapter on a hot cpu; if they're made for cpu fan adapting that's one thing, if they are usually case fan adapters that could mean they aren't made to go on the cpu.

About the Avatar -- I have (slightly) more left on top, and keep it shorter on the sides, and the gray is only on the sideburns, but add some coke bottle thick eyeglasses in dark rims, and it's a better looking version of me.

My 60 to 80 adapter was some kind of transparent blue plastic, packaged by Mad Dog with a chrome wire 80 mm grill, and screws, for a pretty cheap cost. I didn't follow your link. I do skip a lot of those because I'm stuck with dial-up still.

. I've got several of that type of fan adapter - sometimes they work well and others... I'm using an 80 to 90mm fan adapter on the exhaust of my Zippy PSU. That works just fine. A while ago I tried a 70 to 80 on my CPU HS and the way I had to rig it to fit, it didn't seem to make any diff (this is a radial fin type heatsink). On a closed bottom HS, like most OEM ones, a fan adapter can cause enough extra back pressure to foil any gain. I would recommend getting a new HSF with a quieter fan on it. The Spire or Masscool Falcon Rock is a good inexpensive example with a quiet 80mm fan. The base of the Falcon Rock could use a bit of surfacing for best performance but will work much better than stock w/o any lapping. You could even put it on a fan controller to quiet it some more if need be.

Kiwi, it's a 25mm tall lite-blue plastic job from Jab-Tech.

OP, you probably have no clearance issues with using this addapter and where it will mount will seldom see serious temps. It would get pretty warm if you did a quick shut-down after running a long stress test but we don't do that

The worst I've read is poor fit between the sink and addapter causing air to bleed at the edges. This can be reduced if present by using some narrow strips of foam between the addapter and sink or trimming the addapter for the best fit.

The adapters do one particular thing that only an expensive TMD fan can duplicate, and it is how they can cool better than the smaller fan while running slower. The central hub on a standard muffin fan (most of the fans we use are miniature versions of that fan family) makes a "dead spot" right in the middle of the heat sink. With a TMD, there is no hub, the blades are driven from their outer rims. With an adapter, the distance between the fan and the heat sink itself eliminates the dead spot.

There shouldn't be any need to drive the larger fan hard enough to be affected by back pressure. IMO, it's a non-issue.

THEN, anyone on here can backtrack my past comments about the various Speeze, Spires, Masscool "????-Rock" HSF items. I bought several of them without checking in first at Frosty Tech. The Whisper Rock IV came with a totally useless aluminum fan that moved so little air it was like the famous nipples on the boar hog situation. Might as well not have been there.

The Falcon Rock came with a quiet plastic 80mm fan that would do a reasonable job on XP's up through 2500's, at stock speeds (so it ought to be fine for our current OM, here). It was *not* sufficient when used on an unlocked XP 2200 that was running at XP 2800 numbers. It was quiet, it most definitely was inexpensive. There has been a seller on eBay from time to time offering them for $4.95 as a Buy it Now price, plus about $6 shipping. The only thing cheaper was a pair of Cooler Master Xdream II's for $3.50 each plus $4.50 each in shipping cost, from an Overstocks and Surplus dealer.
