Hello guys, its been almost a year since I got my rig.
https://forums.d2jsp.org/topic.php?t=80465742&f=189&p=541607633#p541607633

I went for the Cougar MX330. It had one fan pre-installed. My GPU always got to 80°C+ while playing Fortnite on competitive settings.
So I got four more fans, installed them. I'm pretty sure I got the airflow right too. Front panel both in, back panel out. top both out.

But it didnt got better tbh. Its still getting close to 80? How can that be possible?

My rig is listed above, I did get a 5 2600 tho, not the 8700K

Get the free program MSI Afterburner. With it you can set a fan curve, that can lower your GPU temps.




Also, you might wanna do this as well...


Get SPECCY here: http://www.piriform.com/speccy/download
...get the FREE version from either link listed.
...Speccy is a really nice system hardware/temperature, information Utility.
...simply install it...and run the program...then post a screen shot of the main page of the program, when posting a problem/question on these forums.

I tried, although its not an option for me to have my GPU fans run at 100% to keep my gpu still at 70-75° playing Fortnite, and not even ultra settings..
tl.dr: tried custom fan curve, 100% and GPU still at ~75

try applying new ,better thermal paste to gpu

i did order 1g top quality paste. is 1g ok or do I need more?

Its fine

What's your room temp?
Doesn't matter if you have over 9000 fans in your tower, if the gpu/cpu and your room temp is high. Lower your room heat if you have heater on, remove old thermal pastes and apply new properly

This. No matter how good your fans, etc., you can't get the computer parts lower than room temp. If your room is 80F, you're just gonna blow 80F air all over things in your comp.
Try for a room temp of like 65F, or even 60F.

Also keep the comp off the floor, and make sure there's no dust in the fans or the heatsinks.

Just stick your PC inside a mini fridge. Problem solved
