GPU Fan

(moderation:
So my GTX 650 fan didn't spin up after a shut down to blow out the computer. Flicking the fan has it spinning at some minimum speed, but I still can't run GPU apps.
Any thoughts on replacing or supplementing the fan? First step is to to take the GPU out and make sure I didn't jam dust in a spot I can't see, but after that?

Do a google search for "lubricate video card fan". Check out several sets of instructions before doing the job and pick the best for your understanding and skill level. It's usually quite a simple job if there's a removable plug covering the lubricant reservoir (usually under a peelable sticker).
Even if there is no plug (seems totally sealed) it's possible to drill a very fine hole just big enough for a diabetes syringe. However you do need decent tools for drilling the hole, eg a hand rotated wire drill. You need patience and care so as not to damage the bearing inside. Drill slowly and clear the 'cuttings' regularly until you feel the drill break through into the reservoir. You only need to add a couple of drops of oil. The hole can be sealed with duct tape afterwards. Use a light machine oil like sewing machine oil, not a vegetable oil.

I looked up new fans before
)
I looked up new fans before and they seem to cost too much if you wanted one that works good and I hate to even shut my GPU crunchers down.
So when I plugged in a GeForce 560Ti and the double fans wouldn't work and then both fans stopped and I wanted to keep it running I just shut down and unplugged that card and quickly removed the fan and checked for dust in the sink and then plugged it back in to the pc and on top of the card I layed a little 4in AC fan I had in my stash on top of the sink facing down on it and fired the pc back up with that fan running (those cost about $5) and checked the temp and while running BRP PAS X3 at just under 6 hours the temp has been between 68 and 72 C (5 months now)
And I have had it running like that since then and it is faster than my 660Ti SC
Hey when things work I don't waste time and money on making it look cool

(it is also running vLHC X2 so it could be even faster)
I've ended up using a box fan
)
I've ended up using a box fan for case cooling. HP towers aren't known for cooling and I've added 2 hard drives and the GPU. Turning it all the way up is letting me burn off a single task at a time.
My CPU has been doing better after the heat sink fell off. So little thermal grease on that thing. Might have covered 1/8th of it. Traded my CPU heat for GPU heat though.
I'm going to water cool the next computer.
Water cooling is not labor

Water cooling is not labor free either.
Depending on how the heat sink on your GTX650 looks (there are many models) you can remove the broken fan and attach a bigger case fan with cable ties. I wouldn't use 4 cm, as Magic did, because they're so small they usually run at ~5k rpm to move some air - that's an unpleasant noise. But anything in the range of 8 - 12 cm should do, depending on your heat sink. The GTX650 produces so little heat, it should be easy to "ghetto-cool" it like this.
Aftermarket heatsink-fan combinations usually start at 30€ and require you to take off the stock heat sink.

Well that little fan I am
)
Well that little fan I am using is quiet and I don't even hear it (it is in the box right in front of me) but then I have 5 of these HP boxes right here and at the window at the end of this room I have a big box fan blowing in cool air so it makes the fan noise here and all of mine (well except the laptop) are upstairs away from to rest of the house.
I actually read about many different replacement fans and how people would zip-tie em on to the card but I wasn't going to waste time and money so I tried the fan I had and it works great........of course you have to pay attention and not press it against the MB but I had no problem with mine mainly because the slot is at the bottom of the box so it isn't like some MB where the card is halfway up and has to be screwed to the box to keep it plugged in.
I have this 560Ti and a couple 550Ti and a couple 650Ti's and a 660Ti all OC'd
The bad thing about these cards is the fans are cheap and the plastic case is also cheap and the tend to break right where they screw onto the cards.
That is why I unplugged that cards fans and unscrewed the plastic case and removed it since the fans also work just trying to blow that heat out of the inside of those cheap plastic cases.
The reason I even had that 4in AC fan was I used to use it to cool down my laptop that also runs GPU X2 here and being an 8-core it also runs vLHC X2 and at times 6 other CPU tasks and it would run at 82C but after I replaced the stock HDD with a SDD drive the temp dropped down to 72C (the temp of the GPU card by using GPU-Z)
So I quit using that little fan for that.....came in handy that day to keep this 560Ti OC running 24/7
Of course this is at home and I get to check mine to make sure things are running and they all have the tasks I run ready.
I had no trouble fitting the video cards in these HP boxes even though they are not the large size BUT all the PSU's I got to replace the stock ones are mounted on top of the boxes since they don't fit inside and they work better that way and also keeps the boxes cooler (I also have the side panel off of all of them)
I also never use water cooling since we pay enough money doing this and the stock CPU fans never have failed on these HP's and they have been running for many years here 24/7 (not to mention what they add to the power bill)
When the fan of my ATI 5870
)
When the fan of my ATI 5870 broke I disassembled the card and trough the part number on the fan I found that pchub.com is selling it as a used spare part. Ordered it there, and got an replacement fan which was quite ok, running fine although noisier than a new one for quite a while.
Until I by chance got a replacement custom cooling system for free.
