7870 temps spiking

post #1 of 2
Thread Starter 
I was using my MSI Radeon HD 7870 w/ Twin Frozr III cooling for bitcoin mining and I suddenly around 2 hours into it heard my gpu fans jump to 90% according to Catalyst Control Center, the temperatures were at 86 C, is that too high? I have room for 2 more fans right above the graphics card in my Antec 1100 case so I was wondering if I should put some fans in there, and if I do then any suggestions on fans (120 preferably blue accents or blue LED) and should they push or pull?

temps above 80c is very high. also it looks more like the card has poor application of thermal interface material (TIM). you could try removing the cooler, cleaning and applying better thermal interface material. if thats not possible setup a custom fan profile. for eg: below 50c - 30% ,60c - 50%, 70c - 70%, 80c - 90%.

improve your case cooling too. connect two 120mm fans at the side and two 120 mm fans at the front . all of them should be intake to blow cool air into cabinet. your top 200mm and rear 120mm fan which come preinstalled are exhaust fans.
