I got 2 sapphire 4870 crossfire till now !! 1 of them died now planning to buy new 1 !
soo the reference coller better cooling in vrm ? I tot custom cooler also got cooling for vrm ??
Yes, custom cooler also have cooling for VRM but they're not necessarily good.
Also don't quote me out of context. I said
"Also referenced cooler doing very good job in cooling VRM.". I didn't say better but "very good job". I know for sure Vaporx & Lightning offer very good cooling for VRM which I may say better than other custom coolers but then these are custom boards with better VRMs. I can't say the same for other custom coolers.

No throttling moment at all?

If you run at stock fan profile, sure it may throttling. I use custom fan profile no throttling whatsoever & I have two in my rig. I can maintain both below 80C on the core at stock clock. The only bad thing about them is noise. I'm watercooling anyway, so the noise just for short time.
BTW, anyone with 290/290X custom coolers running card overclocked while gaming, not just benching?
