Please recommend best 140mm and 120mm fans along with advice

Hey all,

So here it is in short, I'm running 3 GTX 980s SLI and the top card is taking the heat hard. Not too ridiculous, but enough to the point where if you let all 3 get to 100% usage that top card gets to 85 eventually.

Anyways, I figured before I invest in water, I'd like to try and give fans the best try I can. I'm only using stock fans so some modifications may get those temps right where I want them.

So I have a 500R case. It has an exhaust in the top back, a 200mm side intake fan, 2 120mm intake fans in front of the drives, and I am using the h100i cooler on top and to be honest I really am not sure whether or not they are now exhausting or intaking.

So here are my plans:

1. I'd like to swap out my 200m side fan with 2 140mm high quality fans. The 200mm kind of misses the top GPU so I think that it may help.

2. I'm removing the drive cage and I'm on the fence as to whether or not it would be worth it to add a 120mm fan where the drive cage used to be facing the GPUs (Reason being, there are already 2 fans blowing towards the drive cage)

3. Add a 120mm fan to the right of the PSU blowing up. I'm thinking this may help with the air coming from the bottom of the gpu which is heating the top, maybe it will cool it off a bit? Not sure.

Anyways,

I need 2 things. I need recommendations for what the best 140mm/120mm fans would be, and then also, is there a way to power them using a molex cable? Because of how my GPUs sit I can't really access any more fan ports. Is there an adapter I can get?

Thank you!

Well the first thing I would recommend it tidying up your cabling in behind the drive cages. That mess of wiring is going to hinder airflow. Unfortunately with how close those cards are together, the top 2 cards are going to heat up the most.

As for case fans Corsair High Performance Series in 120mm trim are pretty good. They move lots of air, the down side, they aren't quiet. Then there are the Corsair Quiet Edition High Airflow in 140mm trim, they move lots of air and are quieter than the 120's. I've never owned Noctua, but I've read plenty of reviews saying they can move lots of air without too much noise.

As for an adapter, you can get molex to 3 pin adapters. You'll want 3 pin fans not 4 pin (PWM) fans or you'll have to get a PWM fan controller. I've seen them at Newegg.
