So the north and south bridge fans are ridiculously loud on this thing, I couldnt find a thin enough 50mm fan to replace the northbridge so I stuck a 40mm fan I had laying around on the heatsink and will see how well it does. Also ordered a noctua 40mm to replace it since the one that is on there is only slightly less noisy.

However the southbridge fan is the worst offender. and its not a standard size it seems, I ordered a direct replacement from amazon - http://www.amazon.com/NVIDIA-Southbridge-Chipset-Cooler-Connector/dp/B00AN8Z8F6/

Until that comes in, I was curious how dangerous not having the fan on the southbridge would be. I took the fan out, which left the metal bottom of the frame for fan (like a weird shaped heatsink) and left it off all day. And it didnt seam to get too hot, unfortunately i took the northbridge fan off as well and it got very hot and system locked up overnight so im not sure which caused the lock up.

So my question is, how much damage can I do if I attempt to leave the southbridge fan off for a few days? If it locks up again I can assume it was the southridge since the northbridge has a fan back on it. Or I could be completely wrong, but someone here probably knows more than I do about this.

Did the new fan fix your problem with less noise? I saw on amazon and was debating whether to try it out.

My friend gave me his old rig that appears to have been a very popular setup (680i SLI w/ q6600) so i could use everything for an HTPC, but the fan on that board is obnoxious! Mine has the heat pipe that has been mentioned on here, but even with that the MCP reaches 80C without some kind of active cooling. That's just in BIOS, i don't want to know what it would get to during real use.

EDIT: I fixed my issues after reading through the original manual (yeah...imagine that) I found online. In the manual it clearly states that if the CPU is not using ACTIVE (aka fan) cooling then the optional northbridge fan becomes MANDATORY. The...

lol, yeah. this board had great reviews at the time though. It was my first build and its still going strong, had a e6400 and now its my home server with a q6600 trucking along like a champ. the fans just barely started getting annoying.

I'm wondering, wouldn't be easier, cheaper and most definitely quieter to just thermal epoxy some heatsinks atop the NB/SB and dump the noise-makers entirely? a heatsink is nothing but some aluminum fins anyways, and the heatsinks themselves could be huge.. probably work better than the fans or the more expensive stock fins. I'm sure the intake fan of most atx cases would work as a replacement fan for the heatsinks anyways

I had an XFX 680i LT with an OC'd Q6600. I used thermal tape to put a heatsink on the southbridge and it worked fine. For the northbridge I used speed fan to turn off the fan and I didn't see any temps over the low to mid 30's for it. The northbridge fan had been relatively quiet but got noisier over time. I had also done a direct replacement for the southbridge fan/heatsink and it was quiet for about two days which is when I put on the heatsink.

I think you would be ok with just the "heatsink" on the southbridge for several days.

I don't remember where I got it, but it looked similar to the 37mmx37mmx6mm listed on ebay. I looked at the picture of your northbridge - it is much larger than the LT version I had.

I meant to say that my replacement southbridge was ONLY quiet for about two days which is why I went to the heatsink.

The computer I got from my friend came with an H60 watercooler, and that is why the temps skyrocketed without the tiny fan. I swapped coolers from my gaming rig (Hyper 212+) and it now runs cool enough to not need a fan.
