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
 
check out the 800 owners thread you can fit a good amount of custom loopage in there and if you dont want to worry about having everything like me im buying the V8 water cooling kit from overclockera cost 180 quid not bad for all the bits.

You get different sizes of kits or you can ask these nice guys to spec you one. im moving from the h100i my self and 8 pack did a comparison showing that the custom loop of the same size rad as the h100i got a lot better temps but allows for expansion which your case would easily support more than one radiator just depends on how self confident or brave enough you are :)

First review of the final (rather than pre-production) Eisberg 240 kit. It seems to be very good, and would appear to outperform the Swiftech H220 kit based on the numbers and relative performance (though it isn't included in the test).

They seem to have fixed the pump, though they complain that it's still very loud at 12V, but practically silent at 7V. Pre-production units were unbearably noisy at any setting.

I'll wait for a couple more reviews, but may well be getting this.
 
Swiftech is about 2c warmer than Eisberg 240 but a much better cooler.. Comes with PWM splitter with molex power for fans and pump giving easy fan and pump control.. and can be expanded withour voiding warranty.
 
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 :D

Swiftech also has PWM controlled pump.
 
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.

I agree. Surely it's more beneficial for the fluid to be at a constant flow-rate rather than fluctuating?

No more reason than there is to slow down your cooler fans when CPU is not working hard.

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.

This.

Also, bearings in fans and bearings and motor parts in water pumps are a totally different kettle of fish. The latter are seriously adversely effected by varying flow rates and pressures, especially these miniaturised ones. It's usually only cheapo AIO watercooling systems that have pwm pumps, because they market it as a 'feature'.
 
pmc25, I don't think Swiftech is a cheapo AIO watercooling company.

Resident, most automobile do not have electric water pumps. My guess of why you do not find many PWM pump is because they are just now moving PWM technology in... even though PWM motor control is industry standard on variable speed motors like drills, mills, routers, etc.

Neither of you want to discuss this subject. You only want to argue.. and I'm not going to argue with either of you any more. I have years of experience in air and water cooling industry. Not just computers. Changing the flow rate of cooling pumps based on cooling demand is standard practice.

Having spent most of my 20s with my head in the engine bays of various vehicles (bearing in mind I'm just in my 30s) and having many friends in the auto industry I can tell you (In the UK/Europe/Asia) that they do.

So I stand by what I said.

Anyway that's by the by, back to the topic.

In response to the original query by Delphy8:

If you've already got a H100i then switching to another AIO that has similar performance with no real gain by one over the other would just be wasting money IMO.


Buying into one of these 'expandable' AIOs whilst you've already got the H100 just seems like a false economy. By all means if it's your first AIO but the H220 and the Eisberg will hit a ceiling of how far they can go in terms of that expansion before you're needing to replace the pump, the rad etc. Might as well just go custom from the off which will save cash in the long term.

If you're wanting to upgrade beyond the H100i then I would suggest that you save your cash until you can double the budget (assuming your current budget is around £100-120) and go for a proper custom loop setup. You'll see better results for your money and your limit free in terms of where you can go with the system after that.
