Thanks.
Anyhow if I got it all right, is there any part I should consider be extra extra careful when touching or try to not touch at all? I try to use my common sense, but sometimes my impassivity or creativity bypasses that. I don't have any anti-static-"bracelet"-thing. I always done like this. Turn of the PC. Remove the power connector from the PSU. Remove the power from the part I wan't to remove, Wait 30 minute's or something and then plug it out. Touching a radiator first. Then when handling the part for example the graphic card, I have tried to be very very gentle and not point my fingers on anything I don't know what it is or even the board itself. But Exactly how gentle do I need to be, can I, if starting with this method, take a pencil made of wood, and brush away dust gently from the card? I never dared except on the cooling parts. Yeah, thanks a lot.
I'll elaborate a little on what I thing may be the problem. First, your GPU is going to be made up of a few different parts.
1. The PCB(Printed Circuit Board). The is the large silicon board with all the bits and bots attached to it.The PCB plugs directly into the Motherboard
2. The heatsink. This is a large hunk of cut metal(mostly aluminum) that is attached to the GPU PCB. The goal of the heatsink is the transfer heat from the GPU Core, and various other bits and bob's.
3. Fan and/or shroud. The fan blows the air across the Heatsink, removing heat from the GPU. Some time's there are shrouds acting as ducts to guide the air in a specific path.
4. I/O backplate. This is the small metal pice that actually bots to the case. The Video outputs are located on this part.
From audio of the video it sounds like the Fan is coming into contact with somthing(such as the shroud or heatsink, maybe even the power wire for the fan itself).
The other possiblity is that the bearing in the fan motor has dried up. The bearing is a part inside the fan that allow's the motor and blade to spin freely with minimal friction. The bearing needs Oil to do this.
There are many video's on you tube about how to take a fan apart to oil it. Its pretty basic stuff too. No large tools needed.
Yes TIM=Thermal Paste. Don't reuse TIM. Always replace it with new.
You don't need anything fancy like a anti-static bracelet. just make sure you reduce the static in your body as much as possible(by not wearing socks on carpet, ect) and discharge/ground yourself by touching a metal part of the case while holding the PCB's. Also, the less you touch it the less chance of frying it you have. You can use Cardboard(cut up cereal box) as a work mat. I would take detailed photo's before you remove ANYTHING from the GPU. Taking one apart is not hard at all, but if your new you might forget simple details like how the fan wire's are routed.
All you really need to accomplish this task for most GPU's are: Small flat head screw driver, Small Phillip's screw driver, TIM, Coffee Filter's, 90% or better Rubbing Alcohol. Some time's the Small Flathead Screwdriver's are handy for undoing the push tabs for the shrouds, Most all the screw's will be Philips head though.
Once its apart its time for the Rubbing Alch. and coffee filter's. Use this to clean the TIM off the heat sink and the GPU core. The rubbing Alch won't short anything out and will dry fast. Work's great for breaking down TIM. Coffee filter's are cheap, and by design are lint free. Once its apart, clean and sat for a bit to dry off some. Re-apply TIM(less is more!) and then assemble it again using the pic's for reference just in case.Take note of the fan. It must be able to spin freely without rubbing on anything.
Last bit of advice I can give you is to take your sweet ass time, Its not worth rushing and do not ever force anything. Always be as gentle as possible. If you do this right nobody should be able to tell you opened the card up in the first place.
I would strongly recommend sending the card maker's Customer Support team an e-mail before. Just asking what they think about the card.
