Silent CPU fan

[elvis]

why use four 80mm fans at high speed when one low-speed 120mm fan does the same job at less than half the noise?

Vantec Aerofan... love that sux0r... but dunno if it'll work on a Xeon. And yeah, a 120mm is nice... but those are hard to mount on most cases I've worked with ... unless it's only on the front bezel.

Elvis: Most of my noise comes from the CPU fan. I'd rather tackle that than drill holes to mount a 120 in there.

I wasn't able to find a replacement fan for the XEON CPU heatsink. Most that are sold are either for P4 or Athlons. If anyone's done this before, please let me know.

I am dealing with the same issue, I haven't played around with ordering new fans, I keep waffling over trying new fans or just going for a new heatsink that I KNOW will be quieter.

If you check out the fans, they have a sunon part number, sunon of course knows nothing about this part number, but you can find the right family of fans, and then match the RPM of the thing. Or you could just wait till I get home from work and find the info.

Sure, I can wait. I'm really surprised that no one else here modified their Xeon fans/heatsinks. Almost everyone who builds Athlons seems to do it.

That's gonna be not that easy I think.. although I haven't got my dual Xeon yet but from what I've read. The new Xeons are running that hot that no fan manufactor wants to recommend their product for them. Unfortunatly you can't put bigger fans on them, because there's normally not enough space.

You still have a couple of solutions:
- if temps are okey.. you can make them spin slower.. I think there are software solutions (on some mainboards you can control the speed of the fan by software.. bios? dunno)
another way of controling the speed is with a fan control.
- watercooling.:D
- putting your PC in a different room. That's what I'll do.. we have all the workstations in a special air conditioned room.

Oh... and check out: this thread in the 2cpu forum (http://forums.2cpu.com/showthread.php?s=&threadid=35459) it's exactly your problem (I think).

good luck..

Thanks Danylyon,

I already combed that forum as well. It seems that some are buying Swiftec heatsinks and throwing 80mm Vantec Stealth fans on them. I have to check whether the iWILL DP533 mobo will accomodate 2 heatsinks or 60mm>80mm converters. Either way, those stock 60mm Intel fans are a nightmare.

sorry not to post the info, I had some car trouble last night which hampered the search for the info.

As for the 60->80mm converters, theya re generally less than effective, and I also haven't found one that would be able to hook into the intel wind tunnel.

ok, my mistake, they aren't sunon fans, they are sanyo denki fans.
the model is 109r0612g4051, but sanyo denki doesn't admit to making such a thing.

however, this fan (http://sanyodb.colle.co.jp/product_db_e/coolingfan/dcfan/dc_fan_detail.php?master_id=680) seems to match pretty closely.

5600 RPM, 39db, and 26CFM of airflow.

sanyo denki 109R0612S4021 seems like it might do just as well with 23CFM airflow, and 33db of noise. That'd put it just above the average noise level for a retail box PIII cooler. However, I'm running 2.4Ghz 533FSB xeons, and I might have more leeway with temps. (rendering and gaming tend to stay below 46C, synthetic benchmarks after about 30min can hit 50C, and I'm guessing that is more to do with case airflow than the actual cpu fans)
