airflow AIO and fan positioning

[JustPeach]

I'm running a ryzen 5 2600 stock and a 1060 6gb.
The case is a Cooler Master MasterBox K500L and the AIO is a Cooler Master MasterLiquid Lite 120.

I have 4 fans in the case, two 120mm ones at the flront (with red LED), 1 in the back (2000rpm) and one the top part of the case(this one is the one that came with the IAO and only runs at 1000rpm).
I noticed my CPU heats a lot while doing heavy work it reaches 90+ºC at times.
I wnated to change the fan and AIO positoning but IDK what is the best possitioning for them.
I will leave a few photos of my case, if anyone could take a look and give a piece of advice I would much apreciate it.
P.S I know the case is filthy I'm gonna clean it tomorrow 
Thanks.

Tubing at the bottom idealy. stop air from being sucked up within the endtanks of the rads.

 

120mm AIO suck btw. Should have got a 240mm for that case, or an air cooler. either of them would cool better than a 120mm AIO.

 

That being said, i would stick that AIO at the back of the case where u have the rear 120mm. Set as exhaust.

Then have the 2 fans at the front as intake.

 

Dust ur case aswell   chances are ur suffering more dust than normal due to the 1in 2 out negative pressure ur running. Setup as above and ull be running positive pressure thus less dust buildup.

That leaves me with one spare fan should I put it in the front of the case? Or should I have two exausting trough the AIO? (one pulling air into the AIO the other pulling it out the case)

Push/pull wont help much. its only really helpful with thick rads.

 

Just run 3 intake at front.

1 exhaust on rad at the back.

 

That will certainly give u positive pressure and reduce dust.

 

If u find ur case is retaining to much heat from the GPU u can always move one of the fans to the top as exhaust.
