Radiator For CPU Loop (?)

Looking to set up a new loop for my chip. This is a general question as I am planning a complete overhaul here at some point. Are there any single 120mm rads that will support and overclocked cpu and do it well? If not , what's the best 2x120mm rad/pump combo and what mounts are available to mount it on the back of my case. Are the Swiftech , Primochill , Feser rads still the best? Please include some linkage where possible.
 
A 120mm will be at its limits, a 240mm will be much better.

After reading so many rad reviews, honestly the more expensive radiators are not worth it for 1-2*C. I like Swiftech, but Im not sure if I want to have everything seperate or AIO like these swiftech drive models

i am probably going to go with a MCR-420 though :)
 
Swiftech offers the best price/performance ratio. It really depends on how far you're overclocking your CPU. Of course, some radiators are better than others, especially ones designed for different fan speeds. Are you going for quiet computing or performance computing? Quiet computing means you want a low FPI (fins per inch) radiator with slow spinning (less than 1500 RPM) fans. Performance means you want a high FPI radiator with fast spinning (greater than 2000 RPM) fans. Of course, a 2x120 radiator will always outperform a 1x120 radiator with the same fans/FPI. Performance of the radiator will also increase by mounting fans on both sides of the radiator instead of one side.

Swiftech pumps are the standard pump of choice. I personally prefer the MCP655, but any pump should be fine for a CPU only loop.
 
Why wouldn't a 120mm with good fans in push/pull be enough for his 775 proc? They run cooler than i7's for the most part and you can use an H50 on them with no issues on a good/great OC.

Anyway if you want your own loop the rasa kit is the best bang for the buck. The only thing I'd change is getting your own tubing, some complain the clear tubing they give you is cloudy looking.

a 240mm is only a few bucks more and gives much better delta temps :)
 
Just to clarify - this loop will be for more than just the s775 set-up I have now. I'm planning on Sandy at some point - when the budget permits. I am under the assumption that high performance is going to bring along the luggage of louder fans(?) Kind of like an all out sports car that rides good :) Performance for me is top of the list but I'd really like to be able to quiet my system down.

Unless I change cases , anything bigger than a 1x120mm will need to be mounted on the back of the case. I'm just not wanting to cut into my Lian Li.

That Swiftech all-in-one is kind of interesting. I'll have to do some research on that. About pumps - I have used the MCP-655 before and really like it. Is there a such thing as too fast of a flow? can the coolant actually flow fast enough to pass through the rad too fast and the heat exchange ratio be dropped?

Is the Heatkiller the best cpu block right now? I have used the DTek before and really liked it.

Thanks for the replies and links guys! ;)
 
I'm unfamiliar with the Swiftech kit, but the XSPC Rasa kits have been selling like hotcakes. I believe the EK Supreme HF Rev 2 is the best block that can be bought right now as per the Skinee Lab tests. The XSPC block is one of the best performing budget blocks as well. For 775 or 1155 a 240mm rad with Gentle Typhoons will work fine you won't need anything too loud.

If you want more info on the XSPC here is an OCN thread for it.

I don't think you can really have too high of a flow-rate, I think it only matters when the flow rate drops down so much that it's barely moving through the system.

I personally use the d-tek Fuzion V2, and in all honesty, the difference between mid-high end blocks are on the order of 5 C or less I believe (correct me if I'm wrong). What matters the most is whether or not the blocks are restrictive. What matters the most temp-wise is the radiator, and how well it can cool the water.

Edit: in fact, all of my blocks are made by D-tek. I have the Fuzion V2 and two Fuzion GFX 2.
 
Wow! That Swiftech rad/pump combo isn't cheap! I also need to do some measuring. I have been looking at the way others have their rads externally mounted and I'm not real sure I can do it with the way the mobo/psu orientation is in my case. The mobo mounts on the opposite side of the case and the psu is on the bottom with the 120mm exhaust in between the psu and the I/O of the mobo. I really like this case but it really makes modified cooling a pia!
