Temporary fan speed increase during menial tasks

I've had a Zalman Liquid Cooling fan for about 6 months now, which does its job of keeping my Intel i5-4670 icy cold, at around 15C doing basic desktop/browser work.

My problem is that upon doing simple tasks, such as using a paint bucket in image editing software, or dragging tables around in Word, my CPU usage will jump from 1% to 20% (no big deal), and the fan will noisily speed up to deal with the sudden increase, before slowing down a second later.

I appreciate my fans consideration for the well-being of my CPU, but is there a way to tone down the cooling a little (to keep it idle at ~25C), and to reduce its responsiveness to sudden changes in CPU usage, perhaps using a function of the CPU usage over the past X seconds?

Cheers.

There should be options to set fan curves vs temperature in your motherboard bios/UEFI. (best way)
If not, a tool such as speedfan will do the same thing only with software. (not quite as good)

I've set every fan speed to minimum in the BIOS.

The fan is plugged into the Chassis Fan slot.

Thanks for the help, by the way

I couldn't say, since I got the entire computer at the same time. All that's the same from my old one is the PSU
