Dual Bay Reservoir

post #1 of 8
Thread Starter 
The purpose of a split dual bay reservoir is to run two separate loops from the same reservoir location correct? Example: splitting the reservoir and having one half connected to a CPU only loop and the other half connected to a GPU only loop, right? No mixing of the waters?

Just wondering. Is this more efficient?

Normally when I think dual bay I mean it take 2 bays on the tower, but yes ive seen 2 pump bay res before.

I havent seen many cases where 2 pumps are needed. If you were to go with a swifttech MCP655 you can run multiple blocks and rads off the single pump and since its a quality pump it doesnt produce much noise.

I guess if you wanted to run each pump at a different speed and have lower powered pumps like the 355 a dual pump res would be what you want..

I have NEVER seen anyone use one of those..

dual bay means that the reservoir occupies two 5.25 drive bays.

You've got that reversed. The 355 is the more powerful pump.

Humafold, you are correct.

The split bay reservoirs, like this one, are intended for people running two seperate loops, i.e. a CPU and a GPU loop.

They are (mostly) not supposed to be used for someone running a single loop with dual pumps although there is one that supports this.

tsm106 is also correct, the 355 / 35x is more powerful than the D5 (MCP655), uses less power and therefore heats the water less (although it runs hotter). The downside is that it is noisier than the D5 and needs a custom top to get its full potential (except the 35x).

The only time the D5 (PMP-450) pushes more water than the DDC (PMP-400) is when there is very low restriction. We never see this in our loops - even a single rad, single block loop.

Yeah, I understand that, my question was about the SPLIT dual bay reservoir. I have a regular dual bay.

Thanks! This is exactly what I was asking. I find it interesting thumb.gif

I use a split dual bay res with 2 pumps in series from martin's diagram below. I chose this configuration for pump redundancy so if one pump fails, the loop can still function with the remaining pump. This configuration works great with my system, but it uses a lot of tubing... so routing tubing could be an issue in some cases.

Yup. This is something I would look to do in the distant future. After I had an M8 and a second GPU. It would take a good amount of time, but 1) I like the idea of redundancy in case of failure 2) I would need the M8 because I personally need the extra space for tubing that up. I'm not that good. wink.gif
