Could You tell me how to change the original chipset fun. I'd prefer to
install passive cooling system.
What kind? How efficient it wolud be?
Thx
I went through the original A8N-SLI Deluxe chipset fan quickly (within a
couple weeks of getting my computer). I wasn't at all thrilled with the
idea of having to remove the mainboard to install the Asus replacement (I
have neither space nor tools here), so I came up with an alternate plan.
My solution was to completely remove the stock fan, leaving the heatsink
in place and mounted to the chipset. Removing the stock fan is easy.
(The only problem is that the enclosure is held on by four very small
screws, and the fan held in place by three even
smaller ones. Because they can easily lose themselves among the other
components if dropped, a magnetic screwdriver makes the whole process much
easier. Finding lost ones and storing them safely outside the computer
easily adds an hour to the procedure, but not doing so risks disaster.)
I then replaced it with a Sunon maglev fan (40mm x 10mm, 3-wire) using
four #4 x 3/4
inch (2.74mm x 19mm) wood/metal screws (NOT machine screws), securing the
screws between the vanes of the heatsink to seat the fan. In order to
have
adequate clearance and visibility, I needed to pull the SLI "bridge" and
the top videocard (I have two XFX 6800 Ultras in SLI mode) and then
reinstall the card and the bridge after I'd installed the fan, but that
was the only other problem I had.
The Sunon fan seems to run faster than I'd like (~13,000 RPM), but I don't
know if that's its true speed or if it actually is running at 6,500 RPM.
It's
very quiet. (I haven't figured out how to adjust the fan multiplier, if
that's even possible. I bought five of the fans while I was at it, so I'm
covered even if it is at the extreme high end of its range.) Everything
seems to be working fine so far.
The advantage to this fix is that:
[1] it doesn't involve removing the mainboard;
[2] it's technically and mechanically easy;
[3] takes about an hour if all goes as planned;
[4] the 10mm-thick Sunon fan mounted on the existing heatsink
provides adequate clearance, even for the twin XFXs.
There may be better solutions, but I know this one works.
When I eventually upgrade from this machine, and if I have the luxury of
time, I'm going to wait until more mainboards are available and have track
records, and then choose the best. I don't want to go through THIS sort
of
problem again. I mean if *I* could come up with an inexpensive, workable
solution, why couldn't Asus do it before they put the board into
production?
According to the reviews, the A8N-SLI Deluxe (when *I* bought mine) was
the
best board available. (There was no mention of the chipset fan problem in
any of the reviews I read.) I'd have gladly paid a bit more to not have
had
the Northbridge chipset fan problem in the first place. This is not the
way for Asus to win friends.
