Replacing fan on 5770 - Page 2

post #11 of 14
Hey link_90, I think those little fans you linked to won't be good enough. When I mentioned replacing the fan only I had something more like the Arctic Cooling 8 (or 9) in mind

or something like a Zalman ZM-OP1 80mm Slim (but I wouldn't use anything smaller than this)

.. or even a normal chassis fan of 8cm or 12cm. It's quite easy and will work well if you get that cover off your cards heatsink. Simple screw the fan into the heatsink letting the screws thread squeeze in between the heatsink fins. It does bend and scratch them but it's only minor superficial damage and should hold well unless the heatsink fins are really flimsy. You could test before hand by getting the cover off and screwing a screw in between the fins and see how well it holds (any screw with prominent sharp threads should do), as long at it doesn't fall/slip out effortlessly once you've put all 4 in it will hold well enough. Then again even some rubber bands would hold it on if you like.

Then you can just plug the fan into the motherboard and even monitor it from there, or just connect it to the PSU and let it run at full speed. Or even splice the wires to the original fan's connector so it's powered by the card.

I once had a 6800GT and it's irreplaceable fans started making a horrible noise so I just pulled them off and screwed on a 8cm case fan and it worked better and more quietly than before for over a year until I sold it and a normal case fan is dirt cheap which was nice. Sure it didn't look "fancy", but for me function comes first lol.

Sorry for the late reply.
Your suggestion seems very good, but I was wondering, what if the card heats up (like when playing) and the fins widen, could the fan fall off?
Also I never thought of removing the cover. I had a quick look and it seems fairly easy, I wonder why Sapphire put it there in the first place. biggrin.gif
I think that if I remove it now I could get a very little improvement in temperatures, not much but better than nothing.
Do you have any particular fan in mind that I can find on Amazon UK?

I have to add that I will probably leave the card as is for about a month or more because I'll be very busy. Since the AMD 7000 series could be coming out early I think I'll just bare with this fan and buy a new card directly. I surely won't be buying the new cards right away (better to let others test tongue.gif).

Sorry, I don't check back that often.

About removing the cover, if you remove it while using the default fan there's a chance it will lower it's cooling ability, as the cover is probably there to make sure the air the fan pushes goes through the fines rather than bouncing off and away, just a theory only testing would really tell the difference.

If the fins widen/expand from heating up they will actually grab onto the screw more tightly since the screw would be between the fins so I doubt that would be a problem if the fins are stiff enough to hold it by a screw to begin with.

Though if the fins aren't stiff enough or if you simply don't like that idea you could just use something like cable-ties, they'll probably last "forever" but will have to be cut if you ever want to remove the fan though that shouldn't be an issue as they're dirt cheap and easy to get.

I wouldn't worry to much what fan you get, but the better the fan is compared to the original the better the card will be cooled. If you intend to plug the new fan into the old fan's spot on the graphics car try get one with the same power ratings, but if you're going to just pug it into the PSU or motherboard you can get pretty much any PC fan you like.

I'd suggest measuring the heatsink to see what size fan would fit nicely. With a guess a 120mm PC case fan could fit easily if using cable-ties to secure it and will work well without much noise.

You could probably do it for under £5 looking at Amazon.uk for a 120mm fan ([ame="http://www.amazon.co.uk/Arctic-Cooling-F12-CPU-Cooler/dp/B002KTVFTE/ref=sr_1_1?s=computers&ie=UTF8&qid=1315311406&sr=1-1"]Arctic Cooling Arctic F12[/ame])

Should be cheaper if it looks like a 80mm fan is a better fit for the heatsink.

Edit, I just saw they have a [ame="http://www.amazon.co.uk/Scythe-Slip-Stream-Slim-SY1212SL12L/dp/B002A97IIG/ref=sr_1_30?s=computers&ie=UTF8&qid=1315312149&sr=1-30"]Scythe Slip Stream Slim 120mm[/ame] for £5.50. It might be a better option if you want to keep the height to a minimum. Just remember thinner blades move less air.

Another Edit lol. Incase you're not using the case in your sig, the CM 690 II, you might want to make sure the fan doesn't extent to much over the card, but if you are using the CM 690 II you shouldn't have anything to worry about as it's pretty big.

If it is a smaller case a fan size like I suggested in an earlier post might be best, Arctic Cooling 9, or any 9.2mm fan. Some alternatives if it is a smaller case...
