Hey guys,

So some of you may have seen my other thread stating I won a $1000 gift card to Newegg from EVGA. Well it turns out that the gift card will actually be to NCIX. While their prices are a little higher, as you know they have a much broader range of WC gear. So I will be doing what I have been putting off, and setting up a loop.

I have read alot of the posts on this board, so I have a decent knowledge of components from reading, just no actual experience. My plan is to cool a new Q9450 and a 8800 GTS 512 using 1 loop, but two radiators. I intend to use the D-tek Fuzion V2 CPU block, and a Swiftech MCP-655 Vario pump. Those are the only pieces I have decided on so far.

My questions are these. I want to put the first 240mm rad in the front of my TT Armor, but I doubt I can use a shroud in that area. Which radiator out of the GTX or the PA 120.2 is going to suffer the least from not having a shroud on it? I know that you need higher cfm fans on the GTX, thats not a huge issue for me, its just an issue of space. The second radiator will probably be located off the back of the case, making it less of an issue, but I will probably get 2 of the same radiators just for matchings sake.

Also, can anyone recommend a block for the GTS? I would prefer a full cover block, but if it is going to be too restrictive, I certainly dont mind using a GPU only block.

I am hoping the 655 wont have any trouble powering this bad boy, and I am really looking forward to this. Any insight or recommendations you can give me would be great, and I appreciate the help.

well you could just grab a 480gtx off ncix and hang it off the back. it would be plenty and you could use a shroud

but if you're set on the 2 double radiators then i'd grab the Thermochill PAs. they're less restrictive than the GTXs and do better with the (usually) thinner low-cfm fans.
although my recommendation comes with a caveat that i've gotten sick of fan noise and went towards quiet/inaudible than performance :P

my recommendation would be a gpu core block, mainly because you can use it later on unless mounting holes take a radical shift. although if you plan on holding onto the setup for a good long while, DangerDen's got their IONE blocks out for G92 GT/GTS that Martin's tested and it's got the restriction of a Maze5 (amazing for an FC block)

Well I would hang the GTX off the back, but I sue poth ports on my video card, and from the looks of it the second dvi cord would get in the way.

Really it would be best to make 2 seperate loops if you really want the best possible temps..but id say the GTX would suffer more without shrouds because the fins on the GTX are very densely packed. Theres the new Swiftech G92 full cover block aswell, or EK make nice gpu block aswell. Also if you are going to run 1 loop i think the D5 would be alright but it may suffer a little as the GTX is more restrictive than the PA rads..You could Run 2 DDCs in series because when adding more block you need more head pressure.

GTX with fans over 47cfm..360 GTX Beats PA.3 w/47cfm Fans...HWlabs 480GTX thermals-Martin...For better performance on any rad I would at least use 86cfm Pana...86cfm Pana

Ok so even on the PA higher cfm fans will perform better then lower cfm? Or am I misunderstanding.

ira-k

Right..They only get ahead of a GTX with sub 47cfm fans..They are rated for 500-600W max dissipation and that using 115 cfm Pana on them and a 10W rad out to ambient delta..You really want to try to keep your rad out to ambient delta at 5C and under for performance cooling....

So if your going to use 47+ cfm fans I would go with a GTX, unless you just want a Pa, they are nice rads, the GTX just works a little better...

No I have no real preferance, just needed to know which one would perform better with no shroud, because I dont think I'll be able to fit one in the front. Is there any benefit for pull vs push in this situation?

Has anyone used the EK Full Coverage block that can attest to how restrictive it is?

ira-k

I did this on a 480GTX.Part-1-480 GTX-Temps W & W/O Shrouds..Pull worked better for me with or with-out shrouds.

Transonic did this on a Bonnie core...He had better temp's on pull with it to. Poll: Push or pull configuration for Radiators

Now with a PA rad it might not make as much of a difference, it has a low fin per inch count compared to a GTX or heater core, so push or pull with it might not matter as much.

Well I'll probably go with the GTX, its a bit cheaper and I dont mind the added noise from the fans. So I'll probably go with the GTX in the front using a pull config with higher cfm fans.
