So I've bought the Asus r9 280, and noticed the vrms get to around 100c. I checked the card to see if there was play in the heatsink and there was, So i put a small clip on the side of the gpu thats oppo from the mobo to depress the heatsink and it dropped the temp to +/- 60c on one sensor. And no higher than 27c on the other sensor that respectivly got to 99 and 70 when stressed. Has anyone else come accross somthing like this?

Probably bad shipping, construction, or handling. Did you buy it off Newegg or amazon?

There is likely a thermal pad between the vrms and the heatsink. It's a pretty common setup on video cards. Thermal pads allow easy contact between multiple surfaces that need cooling (such as the vrms) and it's much better than having the vrms exposed to open air. Compressing the pad as you have done is probably giving better contact and/or easing heat transfer to the heatsink.

VRMs are made to handle high temperatures, low 100s C is actually not uncommon. but regardless lower is always better.

Thermal pads are inferior to using thermal paste like we do on CPUs. Using thermal paste rather than a thermal pad on something like vrms or even vram takes more planning and careful designing (to ensure proper contact with the multiple chips a single heatsink will be cooling) which is why thermal pads get used more often by manufacturers.

(I'm no expert on this subject... if someone knows better, please correct me.)

Is what i've done ok then? I guess what asus has done is put the same dcuii cooler from the 780/ti onto the 280(and likely more). Thus probibly not fitting correctly, i think. Thank you for the fast help and did this last part sound plausable?

And it was bought from tiger, barely on time, and obviously had a heavier box sat on top of it at some point. That being said, the box the gpu was in was in perfect shape and the card otherwise works flawlessly.
