Ditto here - I have this motherboard in a system with fans galore (CoolerMaster CMS stacker case) and have had no heat-related issues whatsoever. Getting Suse to recognize all SATA devices is another matter, however... On Friday 20 May 2005 9:47 am, John Storrs wrote:

I built a system with the same motherboard, with normal fans. Its been running linux over 2 months now with no hardware problems. Sounds like a chipset cooling problem as you suspect.

Hi,

2 months ago I have bought a fanless computer with an A8N SLI Deluxe board. Normally this board has a chipset fan built in. The hardware vendor exchanges this fan by a big heat sink to provide a really fanless system.

Now I have shredded the second board within 2 months. The computer works excellent over about 3 weeks. The last uptime was 22 days. Then I get errors on the 3 sata disks. The disks themselves are ok. Last time we have changed the board and all problems were gone.

I suspect the exchanged chipset fan to be the problem. The hardware vendor assures there weren't any problems with the modified board so far. He claims linux is the culprit. But I think the chip runs somewhere on it's temperature limit and after a half-live of 22 days it decays.

Who is right?

Are there any similar problems known?

Linux can't be the culprit. Linux possibly stresses the hardware more then Windows and that additional stress is too much for the system.

Note that it's really hard to create a fanless *and* performant system.

I'm very sure it's the heatsink on the southbridge that's to blame. There's a reason why the nf4 southbridge is cooled either by water or by heat pipe if it has to be fanless. One possibility I've seen and am going to try out is using the Aerocool VM-101 VGA-Heatpipe cooler to replace the noisy chipset fan. The only problem will be bending the heatpipes as this is a bit tricky.

See http://www.nethands.de/athlon/anzeige/show_pic.php4?cat=motherboard&id=2&uid=37406&sysno=1 for what I'm going to try.
