Setting a fan on top of GPU

post #1 of 18
Thread Starter 
I was wondering if it'd be okay to set a fan on top of my GPU (to cool my northbridge).

After installing a Hyper 212, my northbridge no longer gets active cooling and is getting quite hot to the touch/sensor. I was thinking of taking my old 80mm stock HSF and just laying it on the GPU - it would almost fit perfectly to cool the heatsink of the NB. Even better is if I could like cable tie the fan to the heatsink, but I'm worried about plastic melting onto it. Any ideas on how to mount it with something I can get from the household/hardware store?

I'm thinking of just laying the 80mm fan on on GPU, and slide it in between the GPU and the heatsink, but I wouldnt mind 'taping' the fan to the top of the heatsink to blow down on it if I could get some cheap mounting solution that would be safe. Maybe super glue?

dont do it, melted plastic all over your GPU is no fun. If your that worried, buy a active NB cooler on newegg\\

I would avoid physically bonding anything plastic to a component for a myriad of reasons, however, fabricating or working out a way to suspend a fan over a component is a very worth while approach to addressing the issue... theres a couple flexible wire/fan solutions out in the market, one or two pre fabricated metal brackets, and last but not least... the gratuitous use of the ole' ziptie!

If you really need to, you can always try this...

I'd rather not spend too much money or have to order something, and I'm sure I can mount fans inside the case in some way to keep temps 40-45*C for NB. I currently have a side mounted fan 33-39*C but there is turbulence interference.

So zipties won't melt against the NB?

I had a 80MM fan sitting ontop of my GPU pointing on my NB.
No problems what so ever.

Hm, so I was able to fasten a 40mm fan onto it by taking copper wire, looping it around the heat sink, and threading through the fan (fan is parallel to GPU - when the case is upright, the fan is on the 'bottom' of the heatsink if you understand what I mean by this).

The problem is my temps are even higher than when I had a rattling side fan, which was hotter when I only had 1 stock case exhaust and 1 stock CPU hsf, compared to now of 6 case fans, hyper 212, and a fastened fan to the heatsink. I think the problem now is that the HS on the nb isn't on correct. I dont think the 40mm fan is messing with it at all, but I think somehow the HS came loose, as if I push on the HS hard, temps actually drop lower than ever, instantly.

Need to figure a way to make the HS on tighter. With this fan on it, the NB actually is cool to the touch, whereas before mounting this fan, it was really hot (even hotter when I removed stock hsf for a hyper 212 and didnt have side intake).
