Enough radiator to handle Q6600+8800 gts?

Hum... It's been a while... haven't really kept up with things after I got my rig stable about a year ago.

Any way, I'm looking to upgrade my current rig to something that will handle some video encoding that takes currently 11 hours a dvd, and am worried a little about the cooling. I'm looking at going up to a Q6600 G0 oc'd to about 3ghz (~130-140w) and a 8800GTS 640, so the heat load is going up ALOT on the cooling loop and I'm not sure if it's going to be able to handle it without running the fans at full blast 24/7. I dont mind them auto-reeving up when things get hot in games and such, but I'd prefer to be able to stand being in the same room with it when I sleep.

Currently I have a single Black Ice GT in the top of my case with two Scythe SFF21F's sucking out, a Scythe SFF21E blowing in the front and two low speed Yate Loon's blowing in from the back and top. From some quick skimming, this is as much cooling as most people suggest for a single Q6600 without a video card. There is enough room in the case to mount one 120 rad on the back, and I have a swiftech rad I can put there, but that's about all I have option wise to get more suffice area to keep both the CPU and CPU cool. Would that be enough to do it quietly, or should I just scrap my quad core plan and go with a fast duel core? Also, would the second radiator blowing into the case as an intake be that much worse then blowing out?

Thanks for any help.

With a quad and an 8800 you need at least a triple radiator.

I have a Black Ice GT 360 with 3 Yate Loons on it, as seen here:

Previously, I had an Athlon64 X2 @ 2.5ghz and my X1800 in the loop, and the radiator never even got warm. I'm now running a Q6600 @ 3ghz with the same X1800, and it gets noticably warm, to the point where I've considered putting some more powerful fans on. The load temp on my Athlon64 was about 38c, while my load temp now varies from 50 to 55c on each core. Now, bear in mind that I'm running with my Q6600 undervolted an that an 8800 also puts out more heat than an X1800...

Owch... That makes me worry. There is no way I can actually put a tipple radiator in my case unfortunately. If I had moded it my self (even though I don't have to tools) then I probably would have set it up for one, but as it a double and a single separate are about all I can do... It's the Performance PC's moded Antec p180. I was actually running the current rig on a that single at one point with a little 80mm one on a secondary front intake in the old SFF box with higher OC's, but even now my load temps are about 42c. If I could some how get somehow get a quad core and video card at 50c under load I'd be perfectly happy though.

Those are two places you could possibly do it. The first one is much easier.

Well, it's not that I couldn't, say put a another radiator hanging off the back, but it's that I REALLY don't want to due to risk of damage, portability, noise, and just looks. Also ripping out the front would kill the noise muffler/filter system I built up there, and that's a feature I don't want to part with.

Just had a little fun with the extream PSU calculator... Yeah, I know, not the best but I can rough out my heat output with it.

When I was running my computer peaked out back in the SFF days and before I fried my current MB (it's been limping along for a while running a minimum OC after some bad leaks), it appears I was dumping a little over 180 watts of heat into the coolant loop. This was when I was running a 80mm rad up front with some low speed fan and a big panaflow on the back 120mm rad. Moved that into my current case, and the heat load drooped by 10 watts due to lower OC. Now that I had my major leak from the MB cooling loop, I'm probably down to 150 watts into the loop.

Now, if I left my current video card the same (9800 series coming out soon?), and just took care of the CPU, I'd be dumping something like 190 watts into the coolant loop. Going back to about the same setup on the 120mm rad as I had in the SFF rig in addition to the black ice GT in the top I think I can handle the extra 40 watts more then I'm pushing now.

Now, looking at the swiftech charts with the lowest end fan they tried on this MCR120QP that I'd be tossing in, it shows 75 watts of heat dissipation at a 10*c temperature difference. I'll be running a fan quite a bit better then that on it, so at a 6-7*c difference I should be pushing off that extra heat in addition to what I'm doing now.

Now, toss that 8800 GTX in, and it come out to me having 230 to 250 watts (depending on OC) of power to dissipate, and then I'd be looking into an external radiator or moding to fit a x3 one in the top. I just wish it was easer to add a second removable loop hookup to the thing that I could put on a remote radiator, but it's just really difficult and cuts the flow SEVERELY. I was running "high flow" quick connects and a three way valve in this system about a year ago on my DIY chiller and it just was a lousy solution.

So, in conclusion, I think I'm just going to do the Q6600 right now and worry about the video card a little later.

Bleh, I have a MCR220 (double rad), and I run a Q6600 and a 8800GTX, both OC'd (Check my signature)

My rad has 4 fans in push-pull, tied to a baybus. Really, double rad is fine.

[sir_pyro]

Good gosh... Ok, yeah, this should work just fine then. Thanks!

edit: Wait.... What kind of fans are you using in this push pull? Noise is an issue for me.

[Orcoa]

i'm plannnin on doin the same thing,

with my Q6600 and 8800GTS,
i got a double rad too, but whts that push pull fan thing ?
like a 120mm fan on each side ? with air direction the same way ?

[ares350]

yeah, both sides, one pushign the airin, the other pulling it out, it increases the force of the flow, combats the obstruction that the radiator creates.

[sir_pyro]

Just ordered that panaflow, and the Apogee GTX, and a lot of tubing (I'm going to re-run it)... This is gonna be fun!

No 8800 GTS quite yet...
