Hi, I bought an used sapphire Dual-X 280x recently and I want to repaste it. I unscrewed the four screws on the bottom but it wouldn't come off. I searched for a teardown on youtube and found nothing. Then I tried looking in the forums and found these two:https://forums.tomshardware.com/threads/how-do-i-replace-a-thermal-compound-on-dual-x-r9-280x.1722158/ and https://linustechtips.com/main/topic/233236-removing-r9-280x-heatsink/. I couldn't find anything useful in the "Tom's" forum post but the person who had issues in the ltt forum's got the gpu open with instructions from a link someone posted it the forum which doesn't work anymore (https://www.tomshardware.com/answers/id-2045376/replace-thermal-compound-dual-280x.html). Could someone please help me get this opened because I can't find a way myself.

First lay down a soft towel on a flat surface & work over it.

If you are 100% sure you have the correct screws off, HS to the PCB & not just the screws for the plastic covers, there is a very good chance that if it's the original thermal paste, it may have dried out and turned to a clay like substance which acts like a glue. Use a regular hair dryer, like the one your mom/wife/girlfriend/boyfriend/partner uses and gently warm up where the HS touches the GPU's core. Once slightly warm, it should "easily" come apart. GENTLY give it a GENTLE TINY twist so the old paste "seal" breaks loose. Make sure you have the fan unplugged from the PCB as well.

Pay close attention to how much tension the screws had as you don't want to crank those suckers down when putting it all back together.

What thermal paste are you using? My favorite is Artic MX-4, though good old Artic Silver 5 is good if that's all you have on hand. Remember, a "dab'll do ya" Does your card have thermal pads on the memory or VRM's or just thermal paste under the HS to GPU core?

Thanks for the tip! I'll try it out when I get home and post the results.

Thanks for the tip! The cooler loosened and I could take it off easily after I heated it up! I use the thermal paste included with my 212 X because I'm on a budget lol. I think it dropped by 10 degree's and I can even overclock it with a margin.
