I wouldnt suggest you take off the HSF off your brother's card as that would void the warranty.
It would void the warranty only if they notice it.
As for the size I don't know man, and TBH it doesn't really matter, it's just that I usually want to know things for fact. In some "local" forums here in Spain, a lot of people have measured the size physically and the results are varied. You kow when speaking about mm it's hard unless you use proffessional measuring tools. Let's say the actual lenght is 16mm, it's not too difficult that some can measure 15mm and others 17mm. And the results of ponderating them are 225 and 289 respectively.
So I really don't know what to think. I do know that G92b is smaller than RV770 though. That's undeniable when looking them at the same photo or both them against a coin, for example. And RV770 is said to be 260mm^2, so...
