New IN WIN 303 case = higher CPU temps

Hello people,

I recently moved my rig from a Corsair 500R, to a IN WIN 303. I really love the aesthetic and design of the IN WIN case, but upon moving everything over I noticed my CPU temps are 10c higher when gaming and stess testing.

I have my 5820K @ 4.4GHz with 1.325v (Below avg chip) in my 500R I had this chip under a H100i and my loads temps were below 80c when stress testing and 51-52c while gaming (hottest core)

The same setup in the IN WIN 303 is 62-65c while gaming and over 85c while stress testing. BTW, the gaming temps are taken while playing FO4 and GTA 5.

I thought the issue might have been the H100i, as the LED on the block turned RED and stayed lit, then the LED eventually stopped working. I had a TT Water Extreme 2.0 laying around, so I installed it. The temps have improved 1-2c, but it's still pretty hot. I even tried push pull on both the H100i and TT WE 2.0 and no difference.

If anyone is not familiar with the IN WIN 303, the hot air is vented out of the side of the case at the top. Cool design, but something causing my temps to rise.

Couple of options?

#1 - lower vcore and clock speeds of CPU to bring temps down
#2 - Buy a bigger AIO water cooler - TT Water 3.0 Ultimate - 360mm Rad
#3 - Buy a XSPC Raystorm Pro Water cooling kit


Any suggestions guys?

So intake at the bottom, exhaust at the top. Is the rad setup as part of the top exhaust? Is the rear fan intake or exhaust?

Intake at the bottom, top is exhaust, and the rear fan is exhaust. The Rad is part of the exhaust, and the fan to the top far left blows into the PSU fan, which is also part of the exhaust.

My only guess as far as gaming temps is that the bottom intakes are pushing the hot gpu air past the rear exhaust and the cpu rad is soaking up the additional heat.

Try running just the front bottom intake fan and the rear/top exhaust fans and see if the cpu temps go down or increase. Also while not optimal you could run the rad as intake for a round of tests.

leave side pannel open and see if you get your temps back.

If you get temps back, then yeah, its a design problem in the case.
If temps are the same, then no, it probably is a ambient issue or a heat sink issue.

I don't think it's a case design flaw, as I have the same case and cooled sufficiently solely by air, albeit with a lower TDP CPU, a i7-6700k at 4.4GHz, 1.315v . Temps at idle are low 40s and at load low 70s. I could probably push the clock higher and/or get the temps down even further, but low noise was one of my priorities, and right now it's practically silent with all the fans spinning at low RPM (also my chip seems to be a little voltage thirsty for an i7-6700k and not stable above 4.5 without additional juice, so I didn't bother). Only the GPU fan ramps up slightly when gaming or benchmarking to keep it at ~70C.

My build has 3 bottom intake Thermaltake Riing fans, 4 Xigmatek XOF-F1253 (3 exhaust out of side, 1 rear). HSF is a BeQuiet! PureRock with Noctua NT-H1 applied. PSU is FSP Hydro G 850W. Temps seem to be close to same whether using blower-style GTX 970 or internal exhaust R9 390 (though I'm running the 390 undervolted now to keep the temp low and have a gentle fan curve).

OP's old case may be better, but I'm guessing the issue might be something else. I'd check whether the PSU (essentially in the compartment above the CPU/behind the radiator) is exhausting properly.

that big tempered glass pane is going to store a lot of heat, there's just no way around it. radiant heat too, so it doesn't even matter that you have good airflow.
like i said .. beauty before efficiency.

This pretty much fixed the temp issue. The temps are still a little higher vs. the Corsair 500R, but not much. I like the case, so i'm not sure what I'll do yet.

Anyway, thanks for your input guys :thumbsup:

ok my advice then..

flip the fans so they pull air from the top.
So the top fans are pulling air from outside and not inside your case.

Have the bottom fans as well pull air in.

Cases are not air sealed, so there is very minimal negative pressure effect.
Also your case will not build up pressure either, because again, cases are not air sealed and air will escape anywhere there is a hole.

See if this helps.

I am assuming your fans at the bottom is carrying the heat away from the gpu and pushing it up top where your AIO is recycling it.

So to prevent it from doing that, pull the air at the top in, and drop low rpm / low noise fans at the bottom to just keep your gpu supplied with fresh air.

Thanks, I'll give that a try.

Sorry for the late reply to this thread but i'm new to the forums :) I bought this case as a boxing day treat to myself because I fell in love with it! I tested the cooling in different configs. But I've managed to keep temps between 29-30 deg (Celsius) on my rig. 3 fans pulling fresh air from the bottom, exhaust to the back and top, with 240mm rad top mounted to the right. I have an old school i7 920 Bloomfield @ 4 Ghz buried in an Asus p6t Deluxe that refuses to die. What I noticed is that the base clearance is a bit low and restricted the intake, and by raising the case off the table by 1.5 inches dropped temps that were @ 33 deg Cel to my current 29.4 Deg with ambient being around 25 (my wife likes summer-like temps). Something to try?
