Radiator Restriction

post #1 of 6
Thread Starter 
I'm re-purposing my H220 radiator by adding a 280mm rad in the loop.

I'm concerned about the low flow - high restriction of the H220 radiator and thought about adding a X-Flow 280mm to the loop. I know from research, that the X-Flows are not recommended unless there are build issues, but wouldn't its lower restriction help to lower the overall average restriction of the loop?

I've read reviews on Martins Liquid Lab, Extreme Rigs,Thermal Bench, Swiftech White Papers and of course here, but I'm still baffled. I originally planned on using the HL Black Ice Nemesis 280 GTS but found its flow restrictive according to Extreme Rigs. I know that HL Nemesis 280 GTS X-Flow Radiator is less restrictive than the 280 GTS and I like the design for my build, price point and build quality, but I don't have enough information on radiator flow restriction to make an informed decision.

I originally considered the GTX or the SR2, but they're too thick so I'm stuck with a 30-35mm rad, with slow to medium speed fans in push. I'll be running a EK Supremacy block, EK GPU block, along with a 150mm tube reservoir, de-coupled pump and 3/8 x 5/8 EPDM.

Any help would be appreciated.

What pump are you using?

It's a H220 pump from an RMA a few weeks back.

I think the replacement pump may be Swiftech Apogee Drive II with the H220 Pump Top. It has SATA power, PWM connector and a LED connector which I think is for the ALED lighting control on the Apogee Drive II. My old pump just had a PWM connector that powered the pump off the MB header, so hopefully it's the MCP35X pump that's in the Apogee Drive II. Swiftech Tech Support told me the original H220 used the MCP30 pump in the AIO kits, which was a downgraded MCP50X pump.

I originally planned to use the H220 pump in series with a D5 Vario, but decided to use a dedicated waterblock instead and use the H220 pump de-coupled to a tube resevoir.

I thought the Apogee Drive and the H220 used a DDC variant pump? I don't have personal experience with it, so I would recommend confirming this with someone in the Swiftech AIO owner's club. If it is indeed the MCP30 then it can handle the Nemesis GTS 280 and the rest of your proposed loop. The lower restriction from the EK Supremacy compared to the Apogee Drive/XL blocks will help offset it also.

I had a H220x running a 360 swiftech rad and a GPU uni block. It had no problems, I just got really sick of the sound of that pump whine and went to the D5 Revo from EKWB.

I don't really remember the pump noise, because the Helix fans would drown it out when the PWM ramped them up.

I thought I would try the H220 pump de-coupled first and see how it works out. If it's to noisy or if it can't keep the flow up, it will be easy to plug a D5 into it's place. The D5 is my ultimate goal anyway, so it's strictly a dollar and cents issue now. I really liked the EK-XRES 140 Revo D5 PWM, but decided the de-coupled pump / reservoir would work better in my build.
