![]() ![]() ![]() NZXT CAM doesn't need admin privileges to run (I'm very weary of programs that need it).So the solution I've settled on, as I put in my previous post, is NZXT's fan controller with NZXT CAM. I've tried the motherboard manufacturer's fan control utility, but it doesn't work.And I'd rather not rely on the video card warming up the rest of the system to heat up the main input so that the fans start working harder. I would rather adjust the fans based on the temperature of that, not the CPU or the motherboard. This is not adequate for me because when gaming, which is the most common load I put on it, the hottest thing is the video card. I already mentioned that motherboards only have the CPU or the board itself as the temperature input.And even then I could just use a Y-splitter. A fan hub is pretty worthless to me because most motherboards have enough headers for the amount of fans I have.My motherboard is an ASRock B550 Steel Legend. My bottom intake and rear exhaust are based on GPU temp with a higher fan curve in place.Ĭlick to expand.So as a reference point, I have a Fractal Design Meshify C with 2x140mm fans in the front and a 1x120mm fan in the back. My latest build uses a hub for grouping my front 3x intakes to a single header that are reading my CPU temperature to keep a nice cool quiet wall of air flowing towards the top-mounted radiator and across other components. It will usually be different for every setup ĭifferent case layout, different fan models, different GPU & CPU generating more heat than average, etc.įor the passed 10 years or so i have kept separate fans with separate profiles with some blowing cooler air into my GPUs and others carrying cooler air towards/through my CPU coolers.Ī few of my latest builds have been setup with īottom & front-bottom intake fans and rear exhaust based on GPU temperature,įront-mid/top fans aimed more toward the radiator or CPU heatsink will be based on CPU temp. I haven't tried Corsair's iCUE recently, but Corsair is the only alternative I'm aware of that has a fan controller and last I used iCUE, it required elevated privileges to run.Ĭlick to expand.if your board's BIOS only offers CPU or System as the base source you may want to look into some motherboard control software that may allow other sensors to be read and included. Of note, NZXT CAM which you need to configure the fan controller can also run without elevated privileges. Plus I can adjust the fan speeds while in Windows and running a load to find a sweet spot between fan noise and component temperature. I think I'd rather have my cooling based on the hottest part of the system. The GPU on the other hand will easily dissipate 3-4 times that amount. To put in perspective, the CPU dissipates maybe around 40-50W. The fan controller allows me to adjust the case fans based on the video card temperature, which during gaming I find is more important to monitor and adjust the fans for. Neither of these output enough heat in my system to be of concern. I have two in mine, one before the radiators and one after so I can see the temp of the water going in and out of the rads.I bought an NZXT fan controller because I don't like how your only options for temperature source at the UEFI level is either the CPU or the motherboard (which I presume is the chipset). If you don't have a water temp sensor, you can get an XSPC one fairly cheaply and use a T-fitting to install it in your loop somewhere. However if you just want to know if those temperatures are ok for the component's operation, then yes they are well within safe operating temperatures. ![]() If you can provide water and air temps as well as the component temps during a sustained load (long enough for the system to warm up) then we can give you a better idea of how effective your loop is. These are just examples to help you understand the concept though, so don't read too much into it. Same can be said for your coolant temps, 40C coolant temp sounds high if the air temp is 20C, but if it's 30C+ in the room then it's not that bad at all. But if the coolant temperature is at say 26C then that is a difference of 30C which is less than ideal for a watercooled GPU. For example your GPU is seeing a max temp of 56C under (presumably) sustained 100% load, if the coolant temperature is around 46C then that is a difference of 10C and the coolant is doing a decent job of cooling the GPU, even if the water temp is a bit high. Without those it can be hard to know exactly how good/bad the temperatures are. The delta between your water temp and the air temp will tell you how effectively your radiator/fans are cooling the fluid, and the delta between the water temp and the component temps will tell you how effectively your loop is cooling your components. Do you have a water temperature sensor in your loop? It makes it far easier to know how effective your watercooling loop is if you know the water temp and the air temp. ![]()
