Hey everyone, the fans are really going all out!
Hey everyone, the fans are really going all out!
It's a brand new PC with all the latest components, fully assembled and set up. Just two days ago, I was finishing everything. Even when idle, the wallpaper shows 1100 RPM on the fans and CPU tower fans hovering between 700-800 RPM, which is quite loud. It gets annoying when I watch YouTube or play games—especially Roblox, where the noise is intense. My current fan curve makes gaming feel like an airport, and running Roblox caused GPU usage to spike to around 50-80% while CPU usage fluctuated between 12-20%. I’m not very familiar with PC tuning, so I’d appreciate any advice. I’m also testing it on a Samsung TV via HDMI; let me know if that affects performance.
For new fans, keep the noise level low. If they’re yelling, swap them out. A rapid drumbeat sound suggests cables or wires might be causing interference. If they run nonstop at full power, verify your temperatures and BIOS fan curves. When none of this works, invest in Noctua fans—they’re outstanding and nearly silent (varies by model).
One of the components arrived as a case fan for the Montech 903 base white model (not matching the description on the website). Additionally, the Thermalright Phantom Spirit 120 SE ARGB was used specifically for CPU cooling. The fans are connected in series to the CPU fans, and the case fans are installed into separate Sys_FAN1/2/3 slots.
The coolers are placed well inside, but the PC starts quite loud right away and gets even noisier. The GPU and CPU temperatures stay around 40-60°C, which is normal, and the fans are making a lot of noise.
At around 60°C from a fan curve diagram, the system will use about 80% of its fans. The Phantom Spirit should spin at roughly 1200 RPM when operating at 80%. Montech case fans will run near 1300 RPM at 80%, but lowering the fan curve could bring it down to around 30% at 80% efficiency, reaching 70-80°C. If you set the BIOS to 100% before saving and confirm, your fans might become noisier. Try adjusting fan speeds—case fans should run slightly slower than CPU fans since they tend to be louder.
