80 Rad good enough

[hablis]

Don't want to OC just reduce noise. Will an 80 radiator cool an X2 4200 and a 7800GT better or as well as stock air cooling??

You might have to run your fan on the radiator at a level which is equal to aircooling..... I suggest at least a 120.1 radiator for those two devices as the 7800GT runs pretty damn hot.

Your gonna have to have a screamer of a fan to even keep up with the stock cooling using an 80mm rad... if it's even possible.

Best bet is to go up to a single 120mm rad like rick said.

thanks guys, guess I'll retool.

 

[NickS]

maybe dual 80mm rads

The case (Antec P150) has an 80 in the front and a 120 in the back. I was hopein to put an 80 rad in the front and keep the 120 fan, but I guess I'll switch positions.

 

[Boozer]

or get both 120 and 80 rad's?

^ ^ ^ Sounds like the best idea.

Just another idea to throw out there, you could air cool the video card with the Zalman VF-700 and watercool just the CPU if you wanted to stick to the 80mm radiator. The P150, like the P180 has very good sound dampening, and if you run the Zalman on low speed you probably wont be able to hear it above any of the other fans, and it should cool the card quite well.

The best option however is obviously to watercool them both and fit as much radiator surface area as you can into the case. Keep in mind, if you put a 120 on the back of the case, it isn't like you are losing that case fan, you are just placing a radiator there as well. The fan for the radiator will provide airflow through the case just like the fan by itself did, albeit a bit lower CFM due to the restriction of the radiator.

I would recomend a 120mm rad for cpu/gpu combo. But imo if you are not O/Cing W/Cing is not needed. An X4800 doers not run hot at stock speeds and voltage. I would have to recomend any 120mm heatsink, and for the gpu again the Zalman will do great. Also have you setup a W/Cing setup before? If you not you have to worry bout leaks possible in killing your hardware.

Thanks Vengance01 for the support. I came to that conclusion as I have never set up water cooling before. I wasn't to sure about putting $1500 of my hard earned cash in jepordy of getting wet. I'll go for some quiet A/C setup.

I was gunna reccomend this anyways. Much cheaper, much safer, and much easier. For a while I used a zalman CNPS7700 at 1500rpm and it was dead silent... and still allowed me to OC my opteron to 2.9Ghz at 42C.
