Page 5: CPU and 4xGPU

For a typical CPU and 4xGPU setup the general recommendation is a dual loop configuration.  One for the CPU and maybe other devices and another loop for the GPU's.  This can be easily accomplished with the Double Wide Tower Case from Danger Den.  This is a very demanding setup to cool.

With Danger Den CPU block the flow resistance is minimized as much as possible to allow for better multi-block setups.

Typical Setup:

Cases - The Danger Den Double Wide case.

Fitting Size - Use what you like. The difference in performance between 3/8" ID and 1/2" ID is minimal. Try to stick with 1/8" wall thickness. So 3/8" ID x 5/8" OD or 1/2" ID x 3/4" OD tubing.

CPU Block - MC-TDX (best) or MPC-CPU (good). These blocks are designed for the latest LGA1366, 1156 chips. The 775 quads work great with these chips also as well as the multi-core AMD.

GPU Blocks - Use any of the Nvidia or ATI blocks configured for your card.  These are 100% copper and low pressure loss. Typically 30+C temperature reductions or more are seen on load temperatures!!

Radiator - Black Ice Xtreme, GTX, or SR1. 3x120mm and larger size at least 2 units and likely a 3rd unit. The SR1 is the best performing radiator with 2000RPM and lower fans. The GTX is the high speed fan champion and the Xtreme is a great bargain radiator. The more radiator you can put into the system the better off your temperatures will be.

Fans - Yate Loon Medium - Quiet fan. If you want real quiet go for the slow speed. Just go up a size on the radiator.

Pump - CPX-Pro, DDC, or D5 fixed or variable. All of these pumps are excellent for a single block system. The CPX-1 does not have the power to cool a multi-block system.

Coolant - Feser (Typically one bottle unless using 2 radiators or a reservoir). This is the best option if you want colors. If you don't care use distilled water and some type of algaecide. If using antifreeze type additive use only 5% mixture.

Tubing - Tygon or DD-TFC - The best bend radius.

Thermal Paste - Arctic Silver

Reservoir/T-Line - Many options here. Danger Den has a reservoir (RAD-res) that bolts to the radiator, there are the bay style reservoirs. A popular option is the T-line. Check out the video on the T-Line install to know how it works. If using a T-Line grab a tube plug.

Hose Clamp - Use hose clamps.

Other popular items - Fill Syringe, PSU Bypass Adapter, Tubing Cutter.
