What size of heatercore.....
 

I have a Lian -Li PC-75. Before starting to cut with my dremel and jigsaw on that case, I need your opinion. With a maze 3 block, a DD GF4 block, L30 and 1/2" tubing everywhere, will I see a difference in my temps whether I use:

this heatercore : http://dtekcustoms.safeshopper.com/19/92.htm?956 Dimensions(with tanks) are 6"W x 7"H X 2"Thick.

or this heatercore: http://jpiperformance.com/xlr120radiator.htm Dimensions(with tanks) are 6 1/2"W x 11"H X 2"Thick.

I know that with the XLR 120 Rad has enough surface to run quiet fans at low rpm and still get good cooling. The XLR is a bit too wide for the top of the case so I need to remove some alu in the way. Not a big deal though. The D-tek one fits without having to mod the top at all.

I want good cooling but will not use Pelts. So which heatercore should I use? And If I go with a shorter heatercore like the D-Tek one, I much CFM do I need?

I want silence, good temps but I'm looking for silence mainly.

thx.

I have the DTek core. I am running a maze2 with a xp 1800 running @ 1725 MHZ and my coolant temps only go down 2-3 degrees celcius whether i run the one Panaflow H1A @ 12 or 7 volts. I am confident that will keep your system cool at 7 volts. When mine is at 7 volts my PSU fan is loudest in my system.

Note: you may want to add items to your watercooling rig in the future. The XLR 120 Radiator would give you alot of headroom.

What temps do you get idle and under load?

I believe the Dtek one can be found as a stock core in the heatercore database. Check the dimensions you desire and see if anything pops up. The database is located in a sticky at the top of the WC forum.

Unless you don't like money, always check all your options.

@ 7 volts

Idle
Ambient: 28
H2O: 31
CPU (Dioide) 39
MB: 31

Ambient: 28
Load H2O: 32
CPU(diode): 41
MB: 31

@12 volts

Idle
Ambient: 28
H2O: 29
CPU (Dioide) 36-37
MB: 29

Ambient: 28
Load H2O: 30
CPU(diode): 39
MB: 29

The mb goes down because of the increeased air flow in the case. Rad sucks air from outside and dumps it in case.

Thanks Brian. Well I finally decided to go with the D-Tek. I took some measurements again and looked at what I have to do to make the XLR fit and it simply will not be practical with my psu at the top and all.

So now I have an XLR and Scoop that are brand new to get rid of lol....I posted in the buy/sell forum...I'll wait and see. :dome:
