GTX 1080 FE Temperature & Power Requirements
#1
Hello,

I just bought 2 x GTX 1080 FE to replace my old 2 x R9 280X. I place the cards side by side and not having any spaces like I used to do when using my old R9 280X (I have 4 actually but can only use 2 because of heat issue). When testing cracking hashes using the 2 x GTX 1080 FE, the temperature goes up to 90 Celsius after more than 5 minutes and hashcat aborted.

What temperature should I expect for these 2 x GTX 1080 FE running hashcat? Im getting about max 85 to 87 Celsius doing the same thing with my old 2 x R9 280X cards (non reference) and with the casing side panel open.

Should I be getting the delta fans for this to help with the cooling and so that I can run with my casing side panel close?

I'm planning to get 2 more GTX 1080 FE to make it 4 in total. Will the 1200W PSU be sufficient? How to calculate the power requirement for this.

185 W per card x 4 is about 740 W.

Thank you.

Best regards,
Azren
