A simple tip to minimize space and fittings.

I found a way to fit two 360 radiators in a tight package while minimizing the use of fittings and space.

As seen in picture 1; the top radiator is a standard "U" flow layout which is directly attached to a cross-flow radiator mounted vertically. This allows very tight mounting between perpendicular radiators while using just a single coupler fitting to connect them.

I haven't seen others use this method. Hopefully someone will find this useful.

that is actually pretty smart

I did this with two 420 rads in my ancient Coolermaster Stacker STC-01 :)

Unfortunately most cases don't have the mounting spaced correctly, for example offset mounts in the top. Or some IO PCB in the top of the front.

That's impressive! That's enough surface area to cool a small car engine. What was in the case?

Are those EKWB radiators?

Lukeyy19 3 points · Sep 2018

They're not. EKWB rads don't have any rounded edges.

Also, EKWB doesn't have crossflow rads... or they didn't last time I checked.

Thats a lot of radiator in a small case! What kinda temps you getting on the 1080Ti?

obious [OP] 2 points · Sep 2018

The top right temp probe is the water temp entering the CPU block. The MoBo's red readout it the CPU temp probe.

The GPU usually runs in the mid-to-high 30's.

Nice

Hahahaha that's amazing! Honestly really innovative!

This is a good idea. You could also have used x-flow radiators.

obious [OP] 2 points · Sep 2018

That was actually my original plan. The problem was that I couldn't find a cross-flow rad that had top and side IO ports on both sides.

You don't find that 2 radiators is overkill? I have a cpu and a gpu on the same loop with a single 360rad and it runs a little over room ambient temperature

TheQueefGoblin 1 points · Sep 2018

Can you sketch or post your whole loop system please?

This is an extremely specific scenario. I wouldn't call this a "tip" so much as you just got lucky.

obious [OP] 3 points · Sep 2018

It wasn't exactly luck. I studied the specifications of the case and radiators for quite a while before making the purchase.

Generally, most radiator mounting holes are quite elongated on cases. On the Define S, this allows +/- ~3cm of play letting you slide and abut one radiator end to the other.

Edit: To clarify, I couldn't measure the case until I had it. Like most cases, it only lists the supported rad sizes. Radiators, on the other hand, are usually fully specified with cad drawings. The only dimension I had to measure was the lateral offsets.

I'm glad this worked out for you, and thanks for sharing, but stop trying so hard to sound cool. If you use these specific radiators in this specific case, it works, but this is not a normal scenario, and even then, I would never recommend someone doing this just to save a few fittings.
