But if the airflow is restricted - with a BIG AIR cooler etc. Upgrade if you want to reduce noise or lower temps. Also worth noting that if the CPU TDP is high enough it'll start to output more heat. Just my opinion If your pc runs without overheating with a that single exhaust fan than you have enough fans. Jul 31, 2018; Solution #6 Would i get better temps/ airflow if i changed the exhaust to intake ? i will be getting a new fan when i can afford one You can get a 120mm fan for under $5 if you look around. So like, if you have the same fans, you'd want to intake fans and one exhaust, ideally pulling through dust filters. A single 120mm intake fan and a single 120mm exhaust fan would be more than enough to keep that system cool, so your fan configuration isn't going to be relevant to system cooling as long as at least one is an intake and at least one is You may actually get higher temps cause its not able to dump the heat out of the case fast enough. Tho static pressure does matter, but we've standardized methods and fans, so we just go based on CFM rating using the above formula. If you want more advice on the number of fans, then please post the actual PC specs. The case comes with 1 fan installed in the front as intake and one in the far back as exhaust. If the PSU is top mounted then this would actually work fairly nicely. It's likely more than just fine, build your PC and run it with 4 fans and monitor temps. Mounting a 360 AIO in the Obviously it's not an OPTIMAL situation, having only one fan, just make sure that the one fan is installed in the rear fan location as an exhaust fan and keep an eye on temps until you can at LEAST add a second fan in one of the front intake locations. Please tell me if it would be good if I put a second exhaust fan on the rear? Would it improve the cooling of the case and the air-flow? Please tell me. GPU is 2080 Super (overclocked) and cpu is i9-9900K. Otherwise just as long as the system isn't too high end you're good I still recommend the intake fan, that is the most important, it will create positive pressure that will help the hot air get out anyway.

I recommend anything from deepcool, arctic, Someone correct me if I'm wrong please, but as long as your internals are getting enough air, If your case has dust filters you are probably fine otherwise I would consider dropping one of the top exhaust fans or swapping the rear exhaust fan with one of the top exhausts so the RPM matches. I can't speak to the fan quality, but in general you should try to keep your exhaust and intake fans equalized to minimize the pressure difference in the case. It would probably be worse than 1 fan exhaust, 1 fan intake to be honest. But if you could, get 2 more 120mm fans to add onto that 1 which also comes with the case and put them in the front so you can have fresh air going into your system, because intake is also important. One thing to note - while there is a difference in thermal performance whether a radiator fan is intake or exhaust, this difference can be overcome by fine-tuning your fans. If the CPU temp is fine then you didn't need the extra fan anyways. My CPU temps were usually higher than I'd like but my GPU normally ran pretty cool. The minimum number of fans recommended is 2 – an intake and exhaust fan. a piece of cardboard with a square slot in it sized to the shape of the manifold footprint does great as a makeshift gasket. 3 front fans.

The CPU is an i7 7700. 3 fans for intake on the front, 2 fans for exhaust on top, 1 fan for exhaust on the back. Doesn't stop people from flipping out and building a airflow plan based on just counting fans and only venting from the top and a host of other weird assumptions that are far less important than creating a sensible directed air flow plan. Not to hard to mount but watch out what side the fan intakes air and what side it blows it out. As components reach higher TDPs, 2 intakes and two exhausts are recommended. Reply reply [deleted] • Geiles if you are using an air cooler for the CPU which is pushing a lot of warm air, certain fans cannot exhaust enough of that air through a single exhaust port. (Of course i meant inside of the case but at the back/rear). The case fans work better when they get rid of hot air that collects inside, as you already have fans from the CPU cooler and GPU. If your temps are safe, then you don't really have any issues that require fixing. Have one for inlet and another for exhaust for best results. Soo, could I switch the one in the back to intake? Also, the position for the AIO is good enough? Are the pumps in a good position? upvotes Just trying to lower temperatures here before overclocking more if necessary, here is the situation: 2 intake fans in the front ( 1 is the cpu fan for the AIO pump that has actually 2 fans, 1 on both sides of the radiator), 2 intake fans on the top and one exhaust fan in the back.

As long as you set up some decent fan curves (slower RPMs on exhaust and faster on the intake) and don't mind a bit of faster dust accumulation If you want to know whether 1 fan is enough for a gaming PC, then this article is for you. At most you're likely to experience thermal throttling, and if high enough temperatures are reached the system will power off. More fans are ideal to keep speed/noise down, but would not necessarily cool better. At least in this case, with 6 intake fans, the exhaust fans would mainly guide the airflow and barely improve the amount of airflow. Should be, normally if the case came with a single fan it'll be the exhaust fan. e. Why You Should Care About Your Bathroom Exhaust Fan. So i am building a pc.
