When I took bottom rad outside the case temps dropped by about 5C both GPU and water temp. Water delta was around 10-11C wiith 800RPM when previously it was closer to 15-16C

Take out one of the plates. How do you mean bottom doesn't have best venting?? Its open on 4 sides. You can pull air in through the front or flip the fan and have it exhaust, the honeycomb on the back should provide plenty of open space for air. Also, a very large portion of the bottom is open, even has a dust filter if you choose to pull in air through the bottom. I think the small opening in the glass panel will be a pain to keep clean, lol.

-bottom rad should have been side mounted, glass door does not need to swing from that section

I just wish CoolerMaster would make the MasterCase 7 already from computex

This case is designed to be a dual system case. The glass door on bottom is probably so you can show off both systems. It would be really nice if you could side mount the rad though, I had 4 led fans picked out that are useless for the aesthetics lol.

IMO, the dual system is a gimmick, should've just perfected a single system case because this honestly is a great, beautiful case but it is heavily overpriced

I don't think its a gimmick. It may have been designed more for a rad on the bottom but it does not feel like the second computer in the case was an after thought. I really wish I had this case about 6 months ago. I have a Gigabyte Brix on my wall that i use for all the dedicated servers my wife and I use. It would have been extremely nice to be able to build that server in my existing case. Would have been able to make a much more powerful server, lol.

For the bottom chamber I already pull in air from the front (140mm fan @ 850 RPM) but because of the size of the case it doesn't really affect it much. Reversing it made it worse actually since front fans above started blowing much warmer air into main chamber.
On rad fans are static pressure ones, so they don't have good airflow. Warm air comes up and hits mid plate and yes some does exit at the back through honeycomb and glass window cut-out but there is barely any flow.

I think there is only three options I think, either reverse fans to exhaust downward which is not usually recommended
add another radiator to the front to spread out the heat load, or a bit ugly solution to open mid-plate and put fans on it maybe.

I have spare EKWB 360 PE and 240 PE rads that I could add

Also with 480 at the top there is no space for exhaust fan at the back.

Right now I have:
4 fans in pull at the bottom as inatake (probably going to switch to push)
3 fans in front (original phanteks ones) as intake
4 fans on top rad in push as exhaust
So overall its positive pressure
But since all of them are at 800-850 rpm airflow is probably not so good

Is this still your setup? If so the bottom chamber might be positive pressure(if it is it is by a negligible amount). The top chamber might be negative pressure (again, really doubt there is a pressure differential) . Really should try to accommodate a push/pull on the bottom rad at least, and maybe move top rad to front to make room for push pull.

What do you mean by this? if you have both the mid-plates in then the bottom chamber is very small compared to top! Having the fan on front draw air in is good if you have your rad fans blowing air in. It will help push the air out the back.

You really should consider a push/pull setup if you want to run your fans at a low RPM. I have the rad in the bottom exhausting out and the rad on front exhausting out and my case is barely above ambient. I mention in one of my other posts, but the 5 Phanteks fans that came with the case are all intake fans, 3 on top, 1 on back and one in bottom chamber.

Before you add another rad you should try increasing fan RPM or do a push/pull setup. I have 19 fans in the case smile.gif

Oh, one other thing. I have the small front mid-plate out on my case to make room for the tubing. This helps draw air from top through the case and out the bottom.

I added 1 fan in bottom chamber in the front. and switched to airflow instead of Phanteks (they are static pressure)

4 fans in pull at the bottom as inatake
4 fans in front as intakes (Fractal Design GP14, airflow fans)
4 fans on top rad in push as exhaust

For bottom chamber, yeah it is small but long, so I don't think air from the front reaches the back efficiently. I mean is that since I have 4 fans blowing up and only one from the front to back it doesn't make much difference (maybe 1C)

I am considering adding 2nd set of fans at the bottom to create push pull

Also you're not cooling GPU with water at the moment right? So your rads should be cold. If I just run AIDA64 it's totally cool. I even tried running it with passive cooling for a bit and didn't notice CPU temps increase. I think its possible to do that for longer periods of time. My CPU probably generates at most 80-90W

Since I have 2 x 980 Ti's which consumes 235W each according to HWInfo, and I am drawing about 500-550W from the wall on load.
So overtime, rads and water heats up and blows quiet hot air. Last night I measured 41C in bottom compartment. Ambient in the room was 27C
Top compartment got up to 36C and water was at 41.5C

So, after some more testing (switrched to push at the bottom) still as intake, I did end up putting my spare 360 rad in front (so now it's 2x480 + 1x360
Temperatures didn't change at all. Water still reached 40+C

Even with fans @1800 rpm I was getting 48/42 on GPU and water was around 36C

I am kinda out of ideas. I think next I will try each GPU on its own. maybe there is something wrong with the GPU terminal bridge

Tried single cards at a time, and one does run hotter then the other actually. Wither cooler card I was hitting 43C max with 2 480 rads with fans @800RPM

Water was about 35C on load with a single card, with room temp at 26-27C.

So I guess maybe the fans I am using are not as efficient at 800 rpm, but they seem to be pretty well regarded. They do get loud with these rads at higher rpm.
With higher density rads they were about twice more quiet.

I am thinking of trying out SP120 or EK Vardar fan instead


So I did fix the difference in temps for GPUs (you guys were right about the block), now both run within 1C of each other. And both didn't exceed 50C.
However my water temps still are high, 42C with 26C ambient.

Hi Guys,

I am almost done with my build. I should be done in a couple of weeks, but this is what I have so far.

Everything looks great... but I can't imagine that stacked slim rad providing any thermal advantage. I'd have to assume the added surface area would be offset by the higher air higher resistance imposed on the rad below.

It may be worth testing with and without. My money is on it actually having a negative impact.

Look great ! I can't wait to see your final build and performance smile.gif Are you planning to run 3 rads for GPU ?
