I have a thermaltake v200 case, im worried about the temperatures a little bit, ambient is 33°C and in extreme summers it gets around 47°C, in 33°C ambient my GPU goes at 74-78°C with fans running at 92-94% and cpu goes 65-70°C in gaming but when I take out the side panel the temps go alot lower- GPU at 67°C with fans at 65% and CPU goes around 60°C, kinda crazy but im worried about what will happen when i game in summers and what can be done for better cooling? GPU - RTX 2080 Inno3D stock and CPU Ryzen 5 1600 overclocked at 3800mhz at 1.765v, the build is fairly new

So, since your airflow isnapparently so bad, even if you buy teo fans and make it as exhaust it probably won't change anything as you're pretty much not getting enough air. Curstom modding should do the work.

Hi Kiki, Question for you: Your case has a solid Acrylic front panel, and your front intakes fans are being that correct?

Just looking at the case, your front fans have almost no breathing space to bring in cool-air (maybe a small gap at the bottom?). If you were wanting to go the case modding route, I would say consider modding the front panel to allow the fans to breath and start drawing in cool air for the system to use.

very little space at the bottem and some small holes on right side of the case which I don't think do anything

The issue with the V200 isn't so much the front fans being blocked, it's the giant hole in the top.

Fans work by creating a low pressure area behind the blades, faster they spin the stronger the draw. The byproduct being the forced air out the back. With exhausts, that low pressure area is critical. Unfortunately it's just a non directed area, so will attract the nearest possible higher pressure area, which happens to be those giant fan ports at the top of the case. The exhaust fan is really only dumping heat from whatever is nearby, the cpu exhaust and gpu exhaust, but is doing little to nothing for case temps.

Try blocking the top off with a book or similar. That will force the exhaust fan to draw air from the front intakes, not the top of the case. Creating air FLOW. Which will lower case temps and increase efficiency of the 2 heatsinks, lowering those temps too, especially at idle.

The alternative being to cover just the front 120mm hole and use a second 120mm at the top/rear position and increase the amount of draw from the intakes.

If the air isn't moving in the case, a bunch of holes in the side won't do anything. The reason temps dropped is you removed the side panel, so allowed room ambient air access to the cpu/gpu fans. The purpose of the intakes is to help supply those fans with ambient air, but then you rely on poor static pressure to get it there when there's no pull from the exhausts.

when you mean the big hole on the top, are you talking about the hole with fan mounts and a dust filter? Or something else.

Yes.

The rear exhaust will suck fresh air from that giant hole, just as much, if not more than the air inside the case. By closing it off, you force the rear exhaust to only be able to suck air from the case.

Think of like a McDonald's straw. You want to get a mouthful of Pepsi. You add suction, which creates a vacuum in the straw, Pepsi fills the void. Simple and effective. If the straw gets a crack in it, that doesn't happen, big enough crack and you get no pepsi no matter how hard you suck. All you get is air through the crack. The giant fan ports in the top of the case are no different to cracks in the straw.
