Anyone got a small (40mm) fan kicking around?

I want to cool my Northbridge a little bit but I'm not sure if the current heatsink is glued in place or not and I have very little clearance between it and the CPU cooler:

(yes, I know the cable is untidy, it'll be sorted when I put a fan in place)

I want to mount a small fan, no bigger than 40mm x 40mm to the heatsink itself, probably by forcing screws through the vanes!

Anyone got a small suitable fan that they're not using? If I buy one, it's costing as much for the postage as it is for the fan itself and that seems silly.

40x40x10? Yupski. I'm sure I have one of those. I'll bring it to Cottaging. Be warned they whine somewhat at full speed.

Must admit I never thought of doing that, but then I have the DS4 which has heatpipes (northbridge at 39C right now) so I probably don't need to.

Must make a list of all the stuff I'm supposed to be bringing - it's getting longer by the second.

Oooo, not a Delta? I'm after something fairly quiet if I can find it.

It's a shame I can't easily tell whether the HS is glued in place, if it's not then I could find an aftermarket cooler but it's going to be really awkward (ie board out and main cpu cooler off) to find out.

Nope - akasa. I went to one of my parts boxes and didn't find one, then I came back here and spotted one right next to me. Also found a box of food storage boxes I didn't know I had (having bought another). :/

As for the noise, it's an unfortunate consequence of physics. Fan blades that small have to turn fast to make any difference, and that inevitably causes whistling/whining issues. Try it and see I guess (you probably won't notice with the case on and that big HSF right next to it).

The main HSF is actually pretty much quiet, but with two other fans, the PSU and a pair of hard drives, I reckon you're right!

Thanks Mark
