Hi forum! I have been playing around with my fan configuration to try and get the best possible cooling for my pc. However any way I configure the fans the CPU and GPU temps are always higher with the case closed... I have tried quite a few configurations and the current one is the best I have found so far (sorry for the low image quality!). Its a crappy Dell proprietary BTX case and mobo so flexibility is not high. The 2 x stock dell fans used to be intakes with only the PSU exhausting, however I found that with the CPU exhausting straight over the GPU intake fan it caused it to heat more. So I turned the 2 Dell fans to exhaust and added an extra 80mm fan to blow onto the CPU heatsink, along with 3 more 80mm fans bringing cool air in from the back. Now the 3 exhaust fans do not spin very fast, the 2 x Dell ones are controlled by the BIOS and speeds aren't user controllable AFAIK. Also the 4 80mm fans are on 100% as they are plugged straight into the PSU. I would love to be able to crank those Dell fans higher as it would surely help but they have 5 pin connectors which cannot plug into any other sockets. So thats it basically, is there any way I can get this case to actually cool my components or am I stuck with having to keep the side off all the time? Any input much appreciated thanks! P.S I do not know the actual CFM of these fans but the 3 x 80mm intakes running at 100% definitely pump in more air than is being exhausted meaning the case has positive air pressure when closed.
