Pump questions

[Zarken]

I'm just trying to expand my knowledge of liquid cooling. I have seen a few loops with a pump under the reservoir and another pump in the same loop. I wanted to know if that okay to do? in my mind I'm thinking that must put addeded stress on pump. Any insight would be great.

[Izerous]

Two identical pumps working together is just fine. The performance difference it typically pretty negligible but creates a form of redundancy.

Agreed with Izerous. As long as they are the same models of pumps running at the same speed, there will be no undue stress on either, and if one fails, the other will continue to run.

[Necrodead]

Agreed, I would always use the same pumps on the same speeds.

I did exactly that in an older build a couple years ago. one before the rad and one after. I don't think I gained much as far as performance but it worked great regardless.

Like everyone else said, you'd gain negligible performance but if one pump fails, it wouldn't be catastrophic.

Don't do it. unless you have to separate loops.

I have dual pump tops but is for redundancy, never tried running 2 pumps in the same loop in different locations would see no use in that and may cause problems down the road idea less you used check valves then maybe be ok. If you really wanted two pumps then use a dual pump top and same model pumps as the others have mentioned already.

Totally agreed! Better space efficiency that way too; much less piping and clutter than 2 separate pumps.
