My System Specs

Default Opinions on 3 fans vs 6 fans on a triple rad

Hey all;
My watercooling loop in my main rig consists of:

- SR1 Black Ice 360 rad, 6 Gentle Typhoon fans (25mm top and 20mm bottom)
- Heatkiller 3.0 with backplate for i7 970@4.0
- Koolance NX 580 block for Evga GTX 580 (forget the OC)
- Swiftech MCP 655-B Pump, with EK D5 X-Top rev.2
- EK Multioption tube reservoir, basic
- 1/2in ID tubing
- Corsair 800D case
- Lamptron Touch fan controller

What I am wondering is would I notice a performance difference by moving to three fans from six? I am wondering if the six fans are worth the extra space and noise? (albeit the noise is not much of an issue with these).

Three fans would make it easier to clean, and some more room. I also had a heck of a time getting all the fans on and mount the rad (my old method of using a bunch of smaller screws would not work with the GTs).

I am willing to look into a shroud or even a new rad if it means I can get a slightly simpler setup with the same performance on my cpu and gpu blocks.

Check my BST, I have some shrouds that I have not used.

Thanks Stoanee. If the shrouds are worth it I'll PM ya. Right now, I would have no room for the shrouds unless I remove three fans....

I've found that 1850 Scythe GT's shrouded in a pull configuration nets near identical performance (within 2-3c) to push/pull and push at about the same noise level as a push configuration. (ie the quietest config, at least on AIO kits) Add the added bonus of ease of cleaning and I don't think you'd want anything else for a minimal maintenance folding rig.

Looks like I have some shrouds! Thanks for the great deal stoanee.

I'll try them Ilya. I have two folding rigs here and if I can get the noise level down a bit with the same cooling performance I'll be happy.

Turn three fans off and see what happens. generally, you won't see much of a benefit unless your radiator is stressed.
