Would I benefit from an extra 120mm rad?

post #1 of 13
Thread Starter 
I'm considering adding an XSPC 120 rad standing vertically in the drive bay area in my HAF X with push/pull fans as an intake fan. I want the outlet of my GPUs to go to that rad, and then the outlet of the rad to go to the drive bay pump. What do you guys think?

It would definitely help, but is it needed? What are your temps now?

My ambients are pretty high because I don't use the AC so CPU loads are in the 60s or 70s and GPU loads typically in the 40s.

Hmm.. you're using one 360 rad for a cpu and two gpu's? You'd really really benefit if you could squeeze a 240 somewhere.. but a 120 would help as well.

To really answer the question we need to know your water - air delta. If this is at 10°C or so then yes, more rad will give a noticeable improvement, however if it is already low (<5°C) then you will not get much benefit from it.

Remember that realistically you can only get your water - air delta to ~2°C, so if you are currently at 5°C the most you can loose with that route is ~3°C. Adding another rad is almost never going to hurt performance though; they provide extra cooling and very little restriction.

Given that you are cooling one OC'ed CPU and two 5850's on an RX360 then you probably will benefit from another rad, unless you are running some uber speed fans in there.

Probably not worth the hassle bro, overall I think your temps will balance out to be the same over time. You'd need something a bit more substantial like a 240 to make much of a difference, you might see a 5c drop in load temps.

I only have a 360 right now so if adding an RX120 isn't worth the money then I won't do it
($35 for a used rad, $15 for two CM R4s, $5 for barbs)

I don't know my water temperature but I can give you this information
Ambient 32c
CPU under P95 73c
Rad air in 40c
Rad air out 44c

IMO I would NOT be using T connections as water will always flow through the easiest route and can not be sure if water is flowing through the first card as much as the second..

You know with that GPU loop setup, eventually one of your gpu blocks is going to have higher resistance and your going to loose flow in it. Water like electricity is going to take the path of least resistance, and that loop configuration is a perfect example of it.

Besides that, you need another radiator. A 240 is recommended, a 120 will help.

Both GPU temps are the same under load.
The pump is sucking water in as well as pushing it out at the same time, so it balances out even with the T connector.
