I stumbled on this AIO from Rosewill. It seemed pretty run of the mill until I saw they built the pump into the radiator. Seems most AIO's are either work as intended or such terribly now a days, so I wonder what the pump placement would do to temps.

Pump placement has almost zero to do with temps even in a multi-block loop (I tested with a quad GPU loop + CPU block, D5 on minimum, and two radiators). In a single block loop it literally doesn't matter.

I see, I just thought having the pump in the middle of the rad would impede airflow in some capacity. I've just never seen it placed in the rad fins like that before.

It's a weird placement for sure. I guess if they aligned it with a fan hub such that there wouldn't be much direct airflow over that spot anyway, then it may not be as bad as it looks. Still, I would have thought they would integrate it into the top or bottom instead of dropping it somewhere in the middle.

Oh, go me. I didn't even see that (I assumed it was on the reservoir on the end). It does appear to be in a fan dead spot, but even so, I would bet it steals a very small amount of cooling capacity.

I was merely referring to pump placement within the loop, which doesn't matter at all, really.

Right, the most common pump placement is on the CPU block, it's seen it on the end of the road by the tubing but never dead in the middle of the fins. Looks like they're older model even used a low profile CPU cooler but this updated model seems to go to a larger profile one. I can't find any test results for this one either.

The reason they put the pump in strange places like this is due to astek having a patent for the pump in the block. If they put it in there they have to pay patent fees to astek.
