View Full Version : Is this rad sufficient for the load?

I'm looking at a Swifty 2x120 rad, but I want to make sure it can handle the heat load.

I'll WC a Q6600 and a GTX260 with a MCP655.

Whatcha think?

It depends on your goals. If you're not going to OC and you don't mind some fan noise, that rad will do. But if you're going for more than "a little better than air" you'll want more rad.

+1.

Im WCing ONLY my CPU with a 2x120 rad from swiftech and its 100% ok. But adding a GPU to the loop will need more than a 2x120mm rad !

Edit : Sry i also have the NB on the loop, but its not a very big Heat output part.

i would go with a triple rad or high end double 120mm rad with high speed fans for a q6600 and gpu.

I have cooled exactly that load with exactly that rad/pump. My Q6600 was OC'd to 3600, GPU was stock. With 800 rpm (yate loon's), I had a 12c delta. With 1400 rpm rans (Yate Loon's), I had a 6.5c delta.

So yes, if you don't mind slightly noisy fans (1400-1500rpm) you can get good results with this set up. Of course, more rad would allow you to use slower fans and get better temps :)

This was a vast improvement over air for me... I have a case with less than ideal air flow (Cosmos 1000), and high ambient temps (30c when the a/c is off). Hopefully this is a useful data point for you. Delta's were calculated from load generated with Prime95 (no GPU load), over a period of several hours, with measurements taken every second and averaged. 1 water temperature sensor and 3 intake air sensors.



EDIT: I see you listed load/ambient... so with the same gear, same rad, I was getting 58c load (with 1400 rpm fans) with 26.5c ambient... ie, slightly worse than what you are getting with your TRUE ).

To the OP:

I dunno if water is even worth it. You'll get better temps, but with a nice TRUE and the awesome HR-1 on the GPU your temps MUST be good. If your looking for less noise then you'll need a 120x3 rad and get a good one, with low FPI, made for lower speed fans. XSPC, Black Ice SR1, or a Thermochill. These rads are about 10to 15% better in cooling performance than the MCR series. The MCR is an awesome rad and worth every penny. A MCR 320 is what you need. And for the basic non-complicated loop you mention, geting MCR120 and a MCR220 would work, but pay attention to case airflow. Best temps is always room air to the rad first. You okay with a 320 hanging off the back of the case? Done a LOT, works great. Or you could do like I did, LOL. http://www.ocforums.com/showthread.php?t=604016

You'll have about 300 to 350 watts to cool, maybe a bit on the high side, but underrrading ALWAYS cost more later. Here is a test on that rad you linked to.

Scroll halfway down.
Look at the 300 watt heat load at the bottom. and the blue line, mediums (kinda quiet at full speed)
Your Delta T (water temp above ambient) is 9.3C or so. Not very good. Your GPU would be happy, but your CPU will probably see close to the same temps as your TRUE. To get better temps you'd need fans like the orange line, you got earplugs?

Now, go to Skinnees and look at the Delta T for an MCR320. Thats what your shooting for.

A performance loop for low temps (and usually quiet) is ohh under 7C, under 5 is really great temps for the CPU. Spawn is like under 4C but he's got soo many rads.

I went water becuz I wanted to. Lots more work, but it's fun at a LOT more cost. My new rig is very quiet for what I have, but I coulda done almost as quiet on great air like you have.

You won't get any better overclocks methinks, well mebbe a bit if your temp limited on the CPU, but at 3.6 it's a lot of times the mem or Mobo anyway.

Anyway, here is a great linky to read, many good gides and tests.

Have fun!

My case airflow sucks. Primarily because I'm tired of working within a case, and am going for one of Navig's benches.

You're probably right about the mem/MB being the bottleneck for further OC, but I'm really looking for a quieter system where I can work without a case.

Thanks for the feedback. Parts are on the way. Now I'm just waiting on getting to the top of Navig's list :)
