I will take some pictures soon.
I'm planning to OC my 4890. It is meant to be overclocked
.
Before doing so, I believe I need an aftermarket cooling.
Yet, I have those weird VRM heatsinks that has plastic rivets on it that holds it on the PCB. I believe I need to somehow pop it out or twist it out.
However, I think there's a very high chance that I will damage the PCB as they are very hard and barely fit into the mounting holes.

Anyone has experience with this? or shoudl I just leave them on and hope them could perform better than those Zalman heatsinks?

They are not rivets they are spring loaded push pins, at least that's what i think you are talking about


While pressing down on one , you need to squeeze it on the bottom and then push it out.Also they are fine and i would dare to say better then zalman heatsinks mounted with thermal tape.

So my best bet will be take out the the stock heatsink and apply MX-3 and call it a day?
Well that be safe going for a 950~1g oc? because I don't really know an accurate way to monitor the VRM temp. I also need heatsink on the ram chips, my stock cooler only covers to the GPU, any good choice?
