Bypass Cooling Loop

[Squi11iams]

Would there by any benefit to creating a bypass loop or a loop that would skip all the heating elements in the cooling loop (CPU, GPU, Etc) and go through 1 or more radiators ?

 

I work in the oil and gas industry and we have hydraulic equipment that have bypass loops for the hydraulic fluid which is what gave me the idea.

 

Here is a simple outline of what I was thinking.

 

I am just curious what everyone here thinks about such a design vs just having the 2 radiators in series

id be worried about the bubbles and pressure caused by having two opposite pulling pumps

Honestly, you don't need it. However, theoretically, having a rad in a less restrictive bypass loop will increase your cooling ability, since you will have water cycling through the radiator more frequently. However, that would be a minimal difference, and the $ would be better spent on more radiators for the main loop, or really anything else. Even better fans. I wouldn't do it, unless it's a "because it's cool and I want to" kind of thing, and not a "I think this is worth it for the extra cooling" kind of thing.

Yeah the reservoir would either need to be rather large or pump 2 could be a low speed pump to cut down on the turbulence and also increasing the time the coolant is in the radiator.

Haha it would definitely not be a cost effective measure, but if you only had room for 2 radiators would it perform better all things equal having 1 on primary loop and 1 on bypass

Yes. But it would probably be just as much better if you took the $ for the extra pump and fittings, and put that into fancy fans. Or fancier radiators.

I don't see really any reason why there would be a huge difference in performance but other than the extra cost of the pumps and fittings required, but having rads in series or in this case as a bypass usually does not benefit performance as they are already low restriction for the pumps.
