The other has a cooler master jet flo case fan which cannot be used at full speed because it is too loud. I start by clicking the tab all full speed and thats great for one system where the fans can run at full speed and its not noisy. ![]() ![]() Motherboard manufacturers clued into this and started putting aio_pump headers on motherboards which are generally not controlled but are full 12v and tach, so perfect for the use. I have an MSI B450 Tomahawk MAX motherboard with the latest stable BIOS, and the only fan speed up delay options are 0.1s, 0.2s, 0.3s and 0.7s. BIOS settings for FAN control are under (Advanced Mode) Hardware Monitor. So almost everyone uses the fans on the cpu_fan header and puts the pump on the sys_fan header. Smart Fan 5 Features 6 Temperature Sensors and 5 Hybrid Fan Headers with FAN STOP. There will be no control of the pump by the cpu_fan header (pumps are almost always 3 pin DC, the cpu_fan header is only PWM) and the fans will then respond to case temps which never get above the 50's. How many fan headers does the MSI b450 TOMAHAWK MAX have MSI's website doesn't list the fan headers and I cannot seem to find any high quality pictures to count them 13 1 15 15 Heads up - AK620 CPU cooler fans are terrible Intel Arc A770 Limted editoin 16gb results 1 mo. AMD B450 AORUS Motherboard with Hybrid Digital PWM, Intel Dual Band. If this header detects a low/no rpm signal, the cpu can/will shutdown/refuse to boot to protect itself from possible thermal damage.īecause of this, manufacturers will stipulate the pump goes to the cpu_fan header and the fans/splitter to any other sys_fan header. I bought the board a month ago and was using dragon center to control the fans which had some glitches here and there but was working for controlling my case and cpu fans. Pumps are expected (by the manufacturers/OEMs) to fail first.Ĭpus have their own protective systems, used through the motherboard, one of which is the cpu_fan header. Hi, I have b450 tomahawk and am using 2 stock NZXT 120mm, 1 Phanteks 140mm, and the stock and wraith stealth cooler. These Controllers both come with ports and cables sufficient to control several ARGB lighting devices using standard ARGB electrical signals and the common (4-1) male output connectors (looks. Pumps generally have a MTBF of 50,000 hrs. Fans generally have a MTBF (Mean Time Before Failure or service life) of 50,000-150,000 hrs use.
