Gtx 750 ti (Road to gt210)

Actually I just did this, almost all motherboard temperatures went down around 15-20c

I'm running a Sabertooth z77 and 2600k@4.9ghz Cpu temps are fine, but the motherboard is sending an error that the VRMs temperatures are too high (around 80-85c). Is it fine or do I need to change something? I'm pretty poor so upgrading is a struggle, but with this setup I'm fine for a year or so

I need new gpu bcs i only got 750ti:(
