The 675MX will not work on a HM serie, only a 675M will... sorry . try to sell your card at least.

A 7970M can work in your HM with a modded vbios if you're considering changing your 675MX

normally you can : look at PAU1OW work on it, he was able to put a 7870M in a medion barebone (which is exactly the same msi barebone ) and a 780M in the GT60 0NE just google it .

In my personal opinion upgrading a 680M to a 780M isn't worth the money ! wait for the nextgen GPUs not just overclocked rebrands .

You can reflash your bios directly from the bios menu, make sure you selected the adequate bios AHCI or RAID sata mode and your OS !

Just press DEL enter the bios menu and you'll find the option update bios : plug in your usb and you'll be able to select the file : chose the file that begins with E16F4 and flash it.

My gt60 2OD w/ 780M tops too @93° C in some games , i Use cooler boost 2 to keep my card cool, but I think that since it's a rebranded 680M with an overclock and with the GPU boost 2.0 it's no surprise. But I think that GPU boost autodeactivates when the card reaches temps near 80° C

well, you should flash the latest EC as it sometimes modifiy the fan table making idle stat more silent.

If it's noisy and overheating, Make sure the CPU/GPU is well "pasted" use MX or IC7.

But for enudro/optimus clevo, sometimes the GPU fan in idle keeps running even when the gpu is not used anymore, to deactivate it juste double press the fn+1 (turbo fan)
