how to measure system fans
Can someone tell me how to properly measure a video card fan on an ati radeon 8500 le? My fan has stopped and I want to replace it. I am assuming I leave the heatsink in place and just replace the fan...Correct?
Also on a Northbridge fan, do you measure diagonally like on a monitor or just across? TIA |

If this helps any, I know most fans are in mm sizes(40mm, 80mm...) and are measured along the edges since they are square. Monitors and TVs however, I think they are trying to get a bigger *better sounding* measurement by going with the largest measurment they can(the diagonal).

you can usually find upgraded fans for graphics cards made especially for that card
i know they do this with Geforce 4s at least

Just measure the edge of the fan in mm,it should either be 40mm or 50mm,see how it's connected to the heatsink and look at different cooling specialist online stores and find a fan that will fit.
You can also change the heatsink and fan,if you so desire. |

maybe it doesnt get hot enough to damage it if the fan dies. ATI is pretty smart with things like that, and the cards run cooler than the nvidia counterparts. probably would damage it though if ur running something graphic intensive.

No retention pins on 8500, how do you un-epoxy it?

It's probably held on by thermal tape,how is the fan attached to the heatsink?

It might be safer to just replace the fan...I've seen video cards where the GPU was ripped off...not a pretty sight. Cricket

I'll bet it's even uglier if you are both the owner and the destroyer af said video card.

Here are some links to webpages dealing with heatsink removal: The warmed card, butter knife method The freezer method (slow loading page) The scary Method (I don't recommend doing it this way...if you rush, you can rip the GPU from the card along with the heatsink). Cricket

In most cases you can replace just the fan and not have to remove the heatsink. Normally they are attached with screws or clips. And then take it down ot Radio shack and get a replacement the same size. And if the screws don't line up, you can use the High Temp Melt hot glue to install it.

Thanks everyone, Radio Shack huh, Never would have thought about that one. The ATI fan is a little odd, I will see if they have one.
Nice links Cricket, Thanks!
