What Radiator Should I Buy?

post #1 of 15
Thread Starter 
Right now I have the Swiftech H20 120 Premium water cooling kit and I want to upgrade to a better radiator because I will be adding my gpu in the loop later on. I'm kinda stuck deciding between the Black Ice Extreme II and a 360 radiator.

Now I have a HOT gpu, with the Zalman VF900Cu + as5 it idles 43°C and gets to 83°C on load. That will definitely make my cpu temps soar with the rad i have now. So what rad will keep this setup the coolest?

Atm my cpu idles at 38°C and is at 50° load with my 3GHz o/c. Will I be able to keep those temps with the gpu added in with a new rad?

The larger the cooling element..the lower your temp delta will be. I have a BIX2 120.2....wish I had gone bigger and am looking to upgrade.

That said..go bigger.

The GTS X FLow is better than the bip...

Ok, so I should go with the GTS X Flow then? Any other opinions?

Lower pressure drop through the radiator would mean that a smaller pump could be used..or a pump with less head pressure. A higher pressure pump will make a rad more efficient though..so a Xflow and MCP355 would work well together...but not a GTX and a MCP355.

The decision is yours to make..I would go with a cheaper..larger radiator..like the Xflow and a higher pressure pump like a DD5. Those two together should performa very well and leave plenty of head pressure for your water blocks. More turbulence = better cooling..in the rad and the water blocks.

Ok i see what you're saying. But is there a difference between the XFlow and just the regular stealth gts 360 besides the fitting placement? Because with the Xflow im not sure how I can route the tubing for that.

Xflow = across the rad..one time [hence the reason for the fittings to be at the opposite ends]
GTS/GTX = across the rad twice [dual pass..up and down again..yup both fittings on the same end]

The xflow has the lower pressure drop due to it being equivalent of 1/2 the surface area internally. Well...maybe I shouldnt say that...the surface area could be close, depending on thickness...but its only passing the fluid through the radiator once before it exits.

plus the X flow uses a HW Labs-only special thin fins that are less restrictive to air too--it is a very low restriction rad for both fans and pumps...even the db-1 would be adequate--and even those crappy SilenX fans everyone hates would work

The X flow does sound pretty awesome, but I don't know how I should route the tubing for it. It will go on top of my case so will I have to drill a hole or two in it?
