Webb22 dec. 2004 · A filter will only slow things down. It might be argued that an unfiltered PV results in an noisy controller output, but most processess act as first order filters, and these high frequency controller outputs get attenuated in the process anyway. Note this is true only if there is **no** derivative action. WebbYou shouldn't crank the pump speed too fast or the water won't have time to pick up the heat from the waterblock as well. The latter statement you quoted is frankly speaking pseudo-scientific poppycock. Maintaining …
