Fan setup for 3080 FE?

[Porkchopp]

Hi all,

 

Apologies to start...I haven't messed with fans and airflow in quite a few years, since it was always "good enough" in my last couple parts configurations.

 

I was lucky enough to snag a 3080 FE late last week, and it delivered yesterday. I ran it through its paces with my build unchanged (i7-6700k @ 4.4Ghz w/ CM Seidon 240M, formerly GTX 1070 blower-style, Arc Midi R2 Case) and my temps were....let's say BAD. The GPU itself stayed around 75, but CPU temps when loading Flight Simulator 2020 on Ultra shot up to 95-100C, and opening the case let out a huge amount of warm air.

 

My cooling setup was...probably not good before:

 

• 2 intake fans in front and one exhaust in rear (Fractal Design Silent R2 140mm)
• Seidon Radiator mounted at top, 2 Corsair SP120 High Performance 3-pin on a fan controller, intake
• No bottom fan (used to have one)

This setup, with all the hot air from the 3080 blowing up at the CPU, was not working well, so I flipped the radiator fans around to exhaust at the top. But now I feel like I don't get enough intake. Thinking about adding one more intake fan on the bottom and lifting the case on blocks to give it more airflow. This old post details pretty much what I'm looking at:

 

Does this make sense, given the 3080 FE's cooler design? I am open to ideas about different fans and possibly even a different case, although hoping I can put that off. Planning a new case with new CPU/board, etc. in a year or two. Thanks!

Front intake, top and rear exhaust which I think is how you have it currently. That should be plenty of cooling for you CPU, unless your throwing way to much volts at it, or the water block isn’t mounted well/bad thermal paste spread.

Oh, and if your hard drive trays are still in and not being used, take then out to open up the airflow path.

That is indeed what I have. Was worried it wasn't enough intake. Thanks for confirming it should be good! I may try removing the CPU OC or tweaking it (4.4ghz isn't much of an OC for a 6700K) and cranking fans up. I just did a re-paste but might look into some of the new hotness pastes since my tube is many years old.

Yea my second PC is a 4.6 ghz 6700k, it’s on a hyper 212 evo and never gets into the 70’s in game load. I think fill out with aida64 it’s like mid 80’s. I don’t remember the colts off hand. Maybe 1.35 ish? I have not looked at that BIOS in YEARS.
