Northbridge fan crapping out

I thought about putting this in emergency help, but I think my roommate and I have exceeded our quota for now :)

My northbridge fan is doing that thing where it starts to spin too high off of the base and it sorta sounds like a weedwhacker. The heatsink under it is quite small and passively it wouldn't be worth much.

But, right now I'm not folding (due to the myriad of issues facing my machine right now) and I'm not running any games (at least until midterms are over). So, the northbridge shouldn't get that hot right now anyway, right?

    this happened to my old box (now my brothers box) last week. I noticed it when i was home for the day and saw the NB fan of his KRyA-RAID not spinning. I just ordered up these for $6 + shipping. It ran fine for a good week with just the passiveness of the NB cooler, but with this new cooler, it's given me peace of mind, and it doesn't look bad at all too

    Large, passive heatsinks properly mounted work better than small fan-cooled heatsinks, and are MUCH quieter!

    Save for the CPU heatsinks, I have no heatsink fans in either of my home boxes.

    I had this problem on my old KT7, I just removed the fan of the NB and it worked fine, though I wouldn't really recommend doing that so I recommend you just get something along the same lines as Zalmans NB fanless heatsinks. They are great, silent and cool the chip down nicely.

    Bleh, Anybody in this forum have at least 2800 amd retail sinks somewhere. (i have 8) Cut it in the right size, drill the holes so it fits, lap it and your safe. 30 minutes job tops.

    That's if you have the tools/experience, but for some people it's just easier to order a zalman one.

    I sure can. I actually have one that i have started with but i dont have any "bought" ones. I ran out of discs for teh Dremel. You dont need the Dremel but its easyer. Steel saw is good enough.

    One thing that is VERY important though. Even the original HS/Fan is good enough if you lap the northy. I do 240+ fsb on a original hs/fan on my NF7-S with over 2 volt on it.

    And i DO suck when it comes to mod things. Stuff have a tendency to look very strange after i have done things with them.

    It's small enough to fit between the holes for the spring clips on a northbridge; it will need to be lapped as it's got lips on either side of the bottom of the heatsink that will prevent it from touching the northbridge if you don't lap it...

    I've got one on my NF7-S 2.0, topped by a 20cfm 50x20mm fan, and it does a very good job of keeping the nb cool. Now I just need to lap the NB itself...

    I probably have a box around here somewhre with at least half a dozen active NB HS's with various names on them. If he's that desperate I will send one in exchange for coffee if we ever get to meet.

    Or, try an electronics parts clearing house, like this shop . I am using the HS-70 and HS-75 for northbridges and GPUs respectively. Depending on your board/card layout, may still have to do some cutting. I used a hacksaw. (Yes, a lot of work.) You can attache the heatsinks to the chips with nylon cable ties or Arctic Silver adhesive. Both my vid cards are overclocked from stock 275/275 to 325/315 - no fans on these heatsinks.

    Someone above mentioned that JB Weld will work as an adhesive. Does it have a good thermal transfer rate? Has anyone here actually used JB Weld themselves for this?
