Why exhaust? I figured I could have low case temps and still good enough water temperatures with radiators exhausting but it does seem like a lot of air is recirculating back into the case anyway.

It doesn't but I bought a spare just in case and figured I could put it in the loop for added performance and redundancy rather than have it sitting in a box.

Currently there's 2 rads, top and side. I'd like to keep the current rad placement for aesthetic and maintenance reasons - easy to drain through the GPU block and I have easy access to all motherboard components.

There are a number of other radiator issues that can also degrade efficiency.
-1st, the radiators are not perfect "intake" radiators unless they are air tight to the intake vents. The rule of path of least resistance dictates that a majority of the air going through your radiators (both intake and exhaust) will be recirculated.
*To fix this, use tape to seal off the sides and edges so only air is only drawing from the outside. Ugly but works.
*Its hard to get well balanced air flow through this case unfortunately...
-2nd, going to the first point, the "intake" grills on your case, not to mince words, suck. Not much air flow. This makes point #1 more of an issue.
*To fix this, (extreme but I personally prefer function over form), take it to a local metal shop and have them laser cut out the "vents" on the side, top, bottom and use magnetic filters to cover: https://www.amazon.com/DEMCiflex-Fil...1003990&sr=8-5
*Or brute force it with loud fans (and tape as mentioned above).
*Or remove dust filters.
-3rd, yes, the top radiator will be using hotter than ambient air which will decrease efficiency.
*Not sure how to fix this. Usually using the rear 120/140mm fan as an intake helps but this case doesn't have one
While this pump isn't well known it's surprisingly capable for the laughable price it has. It actually might be close to it's advertised spec of 350-400l/h and 3,5m of head. In the "original" loop with 1 pump and 2x240mm xflow + 360mm rad it had sufficient flow at around 70% max output. Increasing speed beyond that barely affected component temperature (less than 1C difference going from 70 to 100%). Now with 2 pumps at 37% the Barrow flow meter is reading 300RPM (I think it's offset by 90 or so to get the real flow?)
Still, the new, 2nd pump is making a rhytmical chirping sound and is overall louder 😕. Maybe it was faulty from the beginning. Could it get damaged from bleeding the system (it wasn't powered on before the system was filled but obviously a lot of air was pushed through it by the first pump before water reached it). Another issue is that it's run on it's side which I haven't tried with the other pump.
I didn't think the vents would be this bad on this case. I don't think I'll be cutting it apart but I might try some tape.
Oh, and the exhaust vents (with rads) were running without dust filters in place but it obviously didn't help enough.
Any ideas why the images got turned upside down?
