Solution is found to Sapphire vapor-x R9 280X "VRM" over heating and throttling problem GOOD NEWS !!
After searching alot for my new Sapphire vapor-x R9 280X card's vrm overheating problem. I finally found the solution It is actually a bios problem. Old bios cards of this series never have vrm overheat , however with new bios of this series vrm get hot. Especilly when overclocked to high frequencies with like 1.2,5- 1.3 voltages you can see the card goes up to 100-110 vrm heat and throttles. NOW TAKE A DEEP BREATH cause I find the solution.
Sapphire uses 2 different vram types in their cards . And one of them gets hot after a certain level of overclock. and this bios ( the latest one which came with the latest part of these series) is not suitable for especially that vram users. So in a forum (a gpu mining forum actually ) I found the solution. people there mods the bad bios for the new series and makes the vrm's run 20-30 c cooler. for example mine was 90-95 at stress test and now it is 70-75:thumb:
you just need to go the forum and find the correct bios in the topic:

or just use the bios I use for sapphire vapor-x r9 280x:

you can use "winflash" to flash bios in windows 8
now I am enjoying full overclock and throttleless and cool and very high performance card.
I am sure Sapphire is gonna make new bios like these people do and make it officially-solved . but if you dont want to wait sapphire to do it. just do as I tell you above
other 2xx card users of sapphire (and maybe other brands) can also use this as a guide especially this link gives moded bioses for each cards. :
