what case do you have? you do know they are almost the same in size
Swiftech also has PWM controlled pump.They're both intended to be expandable, that's no longer unique to the Swiftech. So the advantage is basically pwm fans / splitter ... so you could say worse cooler (not better), slightly better package?
I wouldn't dream of using the included CM / Swiftech fans anyway, so that's no advantage to me ... Sanyo all the way![]()
I fail to see the utility of that ... you'd never run it at max due to massively diminishing returns and higher noise anyway, same with the swiftech.
No point reducing it from the best compromise under low load, since variations in pump speed will diminish its working life and reliability.

No more reason than there is to slow down your cooler fans when CPU is not working hard.I agree. Surely it's more beneficial for the fluid to be at a constant flow-rate rather than fluctuating?

PWM fan speed control is common practice. Why not do the same with pumps instead of using voltage control on them?
If you look at other water cooling pumps on the market you will see most of them are variable voltage / rpm pumps. It only makes sense to run pump slower when system is not working hard and increase flow as need just like airflow is on cooler using voltage or better PWM.
Do you run your cpu fans at full speed all the time or do you use PWM fans and slow them down when system is not working hard?
Take an automobile or most any other vehicle for that matter as a comparison. You don't run the engine 3000rpm all the time. You use the rpm you need to maintain the speed you need.. and when you are stop at a light you let the engine idle. The water pump speed changes as engine rpm changes.. usually as the engine work load changes because the faster you drive the harder they engine works. Idle pump speed is slow and full work load speed is fast.
Why would you want to run the pump full speed when system is idling and 1000rpm will keep everything cool with pump running quietly?
Most variable pumps on the market as far as I've seen are stepped, requiring manual altering. Laing D5 for example. It's variable sure, but you have to manually change the selector. It's not PWM/voltage controlled by the CPU.
TBH a quick google for PWM water pumps (1st page of results) returns only 2 brands, Swiftech and Restar. There must be a valid reason why all the other manufacturers don't offer PWM control out of the box.
Most automobiles now run electric water pumps which are a constant flow rate regardless of engine speed. If the coolant reaches a certain temp then the radiator fan is activated to aid cooling.
So your analogy is flawed.
Hi all
Anyone know what would be the better one of the two
As I've got the h100i at the moment but want to try a bigger rad
Cheers
Waste of money, stay with the h100i
Can you give us some data to back up your above statement please.
Resident, most automobile do not have electric water pumps.
