Smo quality of a contact surface of the stock cooler is very different on each sample. It is often very bad. That's why temps may be so different.

I did wonder mate, especially considering the difference is as large as this. If MSI are OK with me replacing the TIM then I'll most likely go for it with MX-4. I know it was recommended previously that I don't - but I can't see it being any worse to be completely honest.

In the mean time, here are some photos of my new cards;

youll be fine with putting new thermal paste on as long as its non conductive. a while back, i was told by Svet on the MSI forum that as long as you dont damage anything, your warranty will be intact. he also said, then if you have to send it in, to make sure you \let the CS person know that you have changed the thermal paste. its just to cya if they have to take the card apart. as for aftermarket air coolers/waterblocks. i never got around to asking him about the warranty on that. i assume its still good as long as you didnt damage anything.

ive been using msi cards for years and i always change the thermal paste on them. the ones that i did have to RMA were never rejected.

What type of paste do you use?

Can you use a CPU thermal compound or does it have to be different?

Unless you're going eyefinity, at which point there is a larger hit to performance. But even then I don't think it's massive. (high res single monitor - there's minimal change)

You won't notice a difference on any of today's cards in my experience and reading.
