140 Revo D5 Pump Speed 'revving' despite fan curve config

I'm having a problem where my 140 Revo D5 seems to completely ignore my fan curve set in the BIOS (set to 30% constantly). 

It's seems to be if it gets to around 80c or so, it increases the speed to 100% for about 5 seconds then goes back to the 30% - i don't know if it goes back when the temp has dropped, or if it's just a fixed period (it seems to be about the same amount of time every time). 

I don't know why it's increasing speed when I have it set in the Asus QFAN config to be at 30% regardless of sensor temp....

 

Any suggestions? 

 

Update: It doesn't even seem to have anything to do with temps. Just came out of a game just now, temps have dropped to around 55, and it's done it again. 

I'll try get a recording.

Asus motherboards have safety features that ramp most fans to 100% when the BIOS detects temps over 75 degrees for sensors tied to CPU temperature (iirc). To get around this for a custom loops, you should install a 2-pin temperature sensor for the loop and have your fans and pump tied to this instead (usually called T_SENSOR1)

Recent builds:  Meshify C (Zero Tolerance!) & View 37 (Breathable Quad 2080Ti + 2990WX)

Best documented PC coolants

Older Builds

Spoiler

Full-custom loop builds: Meshify C (Full custom loop SLI), Ncase M1(8700K + 1080Ti Full custom loop)  Obsidian 900D (1950X + Quad 1080Ti) & Fractal Define C (1080 in SLI)

Air-cooled builds Air 740D (1920X + Quad 980Ti) & Fractal Define C (Version Air!)

So turns out you were correct about it being the 75c critical temp that was turning it to full (strange but this isn't shown in the options in Q-Fan)

 

Anyway I tried out AI Suite and Fan XPert, turns out you can override it in there :)
