CORSAIR Hydro X Series XD7 RGB Pump/Reservoir Combo

[VSG]

CORSAIR builds upon its Hydro XD3 and XD5 pump/reservoir combo units with the premium Hydro XD7 using a Xylem D5 pump paired with a flat reservoir shaped to look like three stacked RGB fans. Adding to the appeal is the integrated distro plate to plumb water blocks and radiators for a clean and unique-looking build.

Hippity hoppity your front fan mounts and airflow are now my property.




::EDIT::

And yes. For the record, I am aware of some cases having side mounted and bottom mounted intake fans so its less of an issue these days

Yeah, this is essentially made for glass-fronted, side-intake cases like the Lian-Li O11 series. Still, it's kind of funny regardless

Hi,
To much to make it look like three fans
Pump connections look like a nightmare waiting to happen

Why would the pump connections be an issue? Are you referring to the pump cables or something else?

Hi,
Look pretty weird to me

Besides molex and a pwm what else is this pump powering.

The fake fan rgbs.

As mentioned in the review, that last image is of the other two cable powering the 36 RGB LEDs on the reservoir.

Yeah, looks fine to me. Molex for power (only viable option for a D5), fan header for PWM and rpm measurement, and whatever new proprietary RGB connector Corsair has decided they like today.

There's an adapter for 3-pin, 5 V ARGB control via your motherboard.

Had one of these installed in a brand new Origin PC (owned by Corsair) build, which I received in early March 2022. The temps were not great and flow rate is not ideal because of the parallel design splitting output to cpu and gpu.

My biggest issue is that maintenance is extremely difficult. There are two drain ports at the bottom, using either allows coolant to move from the reservoir directly out the bottom, along with most of the coolant from the radiator return; great there. What’s not great is the distribution plate traps flow from the cpu and gpu blocks. You have to flip your case around dozens of times to get coolant to move through the channels and out the drain port. Great if you want a workout, not great if you want to drain your loop.
I removed the XD7 and put a XD5 in instead. Coolant and CPU idle temps are 5C lower and using a traditional serial loop makes it easier to drain.

All that being said, the XD7 is very pretty. If you don’t have an Intel and NVidia home furnace kit to cool, it would probably be fine, but might not be the best pick for top end components.

That's what irked me about the design of this, I don't really understand why would they go and reinvent the wheel when they could just slapped a pump to a 360 reservoir and call it a day. You can even put 2 or 3 pumps if you need it.

Parallel split of channels is a given with distribution plates though, so that in itself is more a design limitation that also allows for the various components to be plumbed in simultaneously. I don't see it as an issue in itself, the D5 should be fine split 3-ways. If temps weren't good, there's something else going on in the loop- maybe trapped air bubbles, maybe poor contact of cold plates, maybe just bad heat dissipation on the radiator.

If temps weren't good, there's something else going on in the loop- maybe trapped air bubbles, maybe poor contact of cold plates, maybe just bad heat dissipation on the the flow rate is split, so total flow to each block would be lower. I didn’t need to disassemble the blocks, they stayed on the cpu and gpu as it was sent to me from Origin. The same Corsair radiators we’re used. The only change was the XD5 and moving from parallel to serial flow. Of course I had to bend new tube, and probably used less than half the length the XD7 needed, but that would be minimal effect

Don’t get me wrong, I’m not knocking the power of the D5, or the XD7 as a whole. It’s a fine piece of kit.
As for the possible reasons for the temps, I can only assume it’s related to flow rate, as the same blocks and radiators we’re used and were not moved or disassembled; only the pump and hardline was replaced. I can say it took less than half the length of hardline to replumb, which is another downfall of a distribution plate.
If it wasn’t cooling a 12900 and a 3090, two things that run very hot, I think it would be great.

Yeah in that scenario I'd definitely go with a more traditional serial flow loop, I get what you mean.
