Thermaltake Bigwater 760i - Page 3

post #21 of 25
If your case cooling can't pull warm air out, water cooling is the least of your worries there buddy. Tell me, where do air coolers expel the hot air to?

How would three pumps be unable to overcome 50% more rad? To claim that you need a little proof.

I agree about the blocks. However we still don't know what block they will be using.

The pumps dying... is irrelevant to what I'm saying as I've already conceded that point. Even so, it's really too early to tell.

One of the advantages of watercooling is positioning a rad to exhaust air into the room. Place a rad inside a case and allowing less than 50% of its airflow to leave the case will hurt performance. Place a rad in a hot case and the lowest temp possible will be the case temperature. Place the rad will a fresh air intake and lowest possible temp will be ambient.

yes, smaller rads are less efficient for the head loss. These are a chart of Thermochill which are know to have very little restriction. The 120.1 creates .3m of restriction while the 120.2 creates about .35m. The 120.2 has a 15% increase restriction but provides over 50% more coooling.

So... you have 50% more cooling with the three 120.1 rads with three times the pumps to overcome slightly less than three times resistance of the rads.

That's a net 50% increase in cooling with the same resistance to pump strength ratio.

pump stength x 3 and resistance 120.1x3 and cooling capacity 120.1 x3

You come up with a full three times the pump capacity, 2.6x the resistance and 50% more cooling capacity.

Instead.... use one good pump and one good 120.3 rad.... then your better off.

I agree, however for the person that wants decent cooling and NO HASSLES/INSTALL... this is perfect and likely cheaper. Probably better than any other TT/pre assembled/onesizefitsall water set up.

Hey man, I'm with you, custom or nothing, but for the demographic, this is looking great.
