GPU fan problem..

Alright, this GPU is driving me insane! Today I cleaned the old thermal paste on my Sapphire R9 280 Dual-X and I creamed sum Arctic Silver 5 on it. I then started it up and went into furmark and did some stress testing and got pretty good results for about half an hour.. Then suddenly i see the temp go up to over 90 and I took the side panel off, looked at the gpu and saw a nightmare (not really but), one of the fans were spinning veeeeery slowly and pulsating, the other fan was good tho. I've been reinstalling the fan cables and have been restarting the system with no luck.. Once i go in to furmark and stress test the fan fails!

How could this crap happen?.. The fan cable looks good but wtf is wrong? Have i destroyed something or what is this crap srsly? ..

did you plug in the fan backwards?

  • Arctic Silver 5 is conductive so please change for a non-conductive alternative before the inevitable
 

This is straight from Arctic's site:

 

Not Electrically Conductive:

Arctic Silver 5 was formulated to conduct heat, not electricity.

(While much safer than electrically conductive silver and copper greases, Arctic Silver 5 should be kept away from electrical traces, pins, and leads. While it is not electrically conductive, the compound is very slightly capacitive and could potentially cause problems if it bridges two close-proximity electrical paths.)

Oh fu*k! What have i done... Fuuuu.. Piss o man why.. :((( omg fuuuuu! Have i screwed it all up now?.. I got a cooler master paste that i got with my tx3 evo, how do i know if that one is conductive?

Interesting. Thought it was conductive.

Don't worry. You're not the only one.  ;)

Thermal paste is usually not conductive. If it was and would actually touch your PCB and connect any traces your PC would've been dead already, but it obviously isn't, so everything's fine.

Apart from that, the thermal paste you get with CPU cooler is NEVER conductive.

ajahha i know, there is some tiny things around the gpu chip or whatever its called

You probably mean the small things that sit around the actual die.

It is recommend that there isn't any thermal paste on there. If there is, try to remove it. You can simply use some isopropal alcohol and cloth to remove it. These parts are by far not as sensitive as the pins on a CPU socket.

Yup its them! There is some paste on there but i dont have any isopropal alcohol, i got some Aceton (some chemical clean or whatever its called in english.. I dont really know how much pressure the things around the gpu can take.. I make another try tomorrow.. But I dont think that the paste is causing the fan problem, so lets concentrate on the fans instead now!

My first word of warning: do not use acetone. It dissolves plastic (it's how they glue 3D printed parts together. Melt the two pieces with acetone and hold them together).

 

I'd first go and buy isopropyl alcohol, and clean the die thoroughly. You don't need a lot of thermal paste, but slightly more than a CPU would.

 

Second, I'd make sure that you're putting the thermal pads back on the cooler. That can be problematic.

 

Third, this sounds like it could be a BIOS issue. Try booting up and resetting the fan back to default settings. If that doesn't work, look VERY carefully at the fan headers, and try to see if they have any breaks in them.

 

If none of this works, call your graphics card vendor and explain the issue.

Well the only thing I got was acetone but it worked quite well, tried to remove as much paste i could but now i know that to the next time! I know about the thermal pads and the only visible damage to the fan cable was a little slight cut in the rubber around the cable itself. When I get home from school I will try if it works.

Btw, the warranty is void if you remove the pcb/heatsink so thats fakud awp

Alright, got my bottle of isopropyl alcohol now! Anyways, the fan starts to fak up once i hit like 75/80 degrees, or it could be random?! I really dont know what problem im facing so i have no clue what to do.. I cant play any games now so i really need to do something, can somebody help me :(

Does your fan spin normally when it in idle?

Okay.. The reason I said don't use acetone is because you had a chance of quite literally melting your board. That would not have been pleasant.

 

My guess is that something in pcb is being bridged thanks to the heat (fan leads, probably). Have you called your supplier?
