Setup A or B

[Deleted member 24505]

Right first of all, i'm testing rads in, front out, in so positive. temps are better, cpu is ten degrees lower on the max temp, gpu is about 8-10 down. I'm not sure on rads out, front in, as it will be very negative with 4 fans in and 2 out. Wont it just hoover dust, specially from the bottom. As it is now, the heat from both rads goes into the middle and is sucked out by the two front fans, plus there is seeming air flow over the rear sink on the board now too, as i can feel air blowing out of the empty rear fan spot.

Hi,
As it is now pictured will be best.

Didn't you say you remounted the cpu water block to ?

 

[The red spirit]

Why not just measure what happens with both?

I have remounted the CPU block, it was the wrong way around lol

As long as you have fans blowing in different directions, you'll always end up with pockets where the air stops moving. Keep all air traveling in the same direction: it just makes life easier at avoiding this issue.

Well my max GPU temp with it OC'd to 1511 core(which is pretty good) and 1951mem gaming( not arsed about benchies as i never run them) is 46c, and max CPU running at 4.1 all core 1.33vcore is 49c. Very happy with temps and it's very quiet.

If that flow order works for you, keep with it. Most do pump > gpu > cpu >rads > /loop

/tapsfoot waiting for other airflow testing pics (bottom/front in > top out)

Case is looking from the top, so as in the pic, bottom-left. Top-right. right-front. board is flat, pic is looking down in the top.

I did loop like this as the order does not matter and its got a better flow to the loop instead of having tubes crossing each other.

there won't ever be stuck air in that system, way too much turbulence and no pressure on the back / it will all just flow out of the back of the case... also that front fan is an intake.

Hi,
Current fan setup is on post #29

 

[Aquinus]

Option C. Mount your RAD fans to be pulling air through the rads and directly out of the case. You want to always remove heat from a PC, never inject it back in. Thus:

Honestly, I think that this is probably the best configuration. Doing an intake on the radiators is putting warm air inside the case which is not ideal. Reversing it will keep the temperature in the case lower. So I agree with Lex on this one.

Intake on radiators is the best for the core component temps and is the best way to build a loop. Cold air on radiators makes a massive difference. The only time I would do exhaust through a radiator is when you have no other exhaust fans in the system.

 

[Deleted member 24505]

I don't think it will make much difference pulling cold air from outside, any heat generated should exhaust fine through the two front 140mm fans. My temps are great. would they be any better if i set it up the opposite way.

Front fans are exhaust, i did post an updated pic.

Only way to find out is trying

Uh, your CPU block is wrong. The port marked "In" is now the outlet based on your flow markings:

Most likely the cooling block manufacturer designed the water channels for optimum flow in a certain direction. You are going the opposite way.

I don't really see the logic of sending hot water directly to the pump nor would I inline two radiators.

Ideally, the most capable radiator should accept the hot exhaust from the GPU (the component which generates the most heat) and the CPU should be outputting to the other radiator.

Cooled water from one of the radiators should be supplying the pump-res combo. The pump will last longer when it is moving cooler water.

But hey, it's your gear, your money, your ears. If you are happy with how your loop is cooling your components and you are satisfied with the acoustics then your job is done.

I did switch the block around, i did mention this in an earlier post #29
What about if i do it like this instead?

The reverse flow (yellow arrows) makes far more sense.

This follows the flow established by the CPU block manufacturer. The pump is receiving the coldest coolant in the loop.

I can't tell from this picture if the GPU cooling block has a recommended flow direction but typically the port on the right would be a more logical exhaust. Also I don't know which port on the pump-res combo is supposed to be the output but it should be clearly marked by the device manufacturer.

here's a pic of the GPU block. I will turn off and switch the flow, won't take long.

Done, pump is getting cool water from rad. pump-rad-GPU-CPU-rad-pump
temps with revised loop

I think the 2600x is bottlenecking the 980ti though. only 65% load in games. Would it help it i don't OC the GPU? CPU@80% GPU@65% CPU is running at 4.1 manual OC all core, shall i just run it on auto?

Hi,
You keep sketching on the old pictures that's why people get confused on your current setup.

 

[Deleted member 24505]

Heres how my fans are setup.

 

[cvaldes]

It's difficult to comment on your fan curve unless you tell us what is plugged into the CPU_FAN header.

And what is plugged into the other motherboard fan headers?

Motherboard manufacturers include multiple fan headers because it usually doesn't make sense to run all fans based off of the CPU temperature. For the other fan headers, ASUS allows you to pick a different temperature source.

The only temp sources i have are CPU and Motherboard, but as the motherboard is pretty constantly lower than the CPU I don't think there is much point using that as a source for the fans. i have 2x140mm NF-A14 on the 280mm rad running off the CPU header, 2x140mm LL140 which are running off a corsair hub thing, sourced from a chassis fan header. and 2x120mm on the 240 rad running off the cpu_opt header. I think it is better this way, strangely the pump cleared air really quickly this way too.
My temps are really good, there is air blowing out of the back empty fan spot, which i reckon will cool the Motherboard reg heatsink too.
Here is a pic as it is now, I don't think it will change from this layout.

So, the top rad is cooling the water that goes into the reservoir ?
