On my primary gaming build, the GPU radiator fan curve maxes out at 950 rpm, the GPU temperature at 63 ☌. It's a balance between heat dissipation and fan noise that you must decide. It's not my computer and I'm not in the same room so I don't care how you set your fan curves. If you're happy with your temperatures and fans reaching 100% speed then leave them that way. Personally, I never let any of my fans (whether they be radiator, case, or graphics card) run at 100% because I care about acoustics and I hate headphones. For my two custom loop builds, I also set the GPU radiator fans with the BIOS. With the exception of air-cooled graphics cards with the stock cooler, I set fan curves in the BIOS, not a Windows application. What's your ideal room temperature? 22 ☌? 25 ☌? 28 ☌? Plus each person has a different usage case, different applications they run, even during idle. plus different operating conditions (ambient temperature due to location, season, whatever). Everyone has a different idea of what is acceptable in terms of temperatures and fan noise.Įveryone's DIY build has different components: case, CPU, GPU, PSU, motherboard, chipset, RAM, drives, accessories, cooling solutions, etc. The main thing is that you're happy with your fan curves.
