| Summary | 0002184: Oscillating fan speed at idle | ||||
| Description | I just downloaded Speedfan 4.49 for the first time in years, hoping to be able to control 3 new GentleTyphoon AP14 radiator fans based on BOTH my cpu and gpu temp - entirely possible using the latest version of Speedfan. At the moment my loop is in pieces on the floor here so as a test I tried controlling my standard Intel CPU heatsink fan using a Speedfan 'Advanced Fan Control': http://i39.tinypic.com/30w5nk4.jpg I thought this was working as intended because any increase in the load on CPU or GPU results in the fan speed increasing as I wanted, however there is a problem... Over the course of around half an hour, at idle, I produced this fan speed chart: http://i42.tinypic.com/2hcopwo.jpg These are the associated temps for the same period: http://i39.tinypic.com/kcfhuv.jpg As you can see, there is a badly oscillating fan speed being produced by Speedfan at idle. I don't get this with the Gigabyte Smart Fan application that came with my motherboard, but then I don't get the ability to control fan speed based on two temps with it either Is this a known issue? My complete setup: PSU: Antec HCG620 Mobo: Gigabyte Z87X-UD4H CPU: Intel 4770K GPU: Sapphire 7970 Ghz Edition Storage: Samsung 840 SSD + 3 x HDDs Case Fans: 2 x Scythe SlipStream 800s Radiator Fans: 3 x GentleTyphoon AP14s Radiator: Thermochill PA120.3 Pump / Res: Laing D5 with XSPC reservoir top Blocks: YBris Cooling 'Black Sun' on both GPU & CPU | ||||
