Koolance XC radiators (54mm @ 30fpi)

post #1 of 6
Thread Starter 
Hi everyone smile.gif

I'm about to start on my first custom water cooling system.

My intentions are to overlock both CPU and GPU, so maximum heat dissipation is first and foremost.

Whilst looking for hardware, I discovered the Koolance XC rads, and was quite impressed with the specs.



http://koolance.com/hx-120xc-radiator-1-fan-120mm-30-fpi-copper



There is very limited information on these rads, even on the koolance site.

I was wondering if anyone knows anything about these rads.

How do they perform in comparison to other brands? Would you recommend something else?


Thanks biggrin.gif

I had a Koolance 240, the 30mm version, and that 30 FPI rating is a lot more restricting than you would think. To get even decent air pushed through, I needed to run my AP-00s at a pretty high RPM == more noise. Not only is it just 30 FPI but the thickness is nearly 60mm, meaning there is plenty of room for air to stall and slow down with the added obstacle of going through such a high FPI rating. Check out Bundy's round up of radiators. Even though they are 360, you can still gauge the cooling capacity of anything lower. Check the 600 RPM chart, difference between a ST30 vs. the Koolance 30mm 30 FPI radiator. There is almost a 8c difference in the temperatures recorded. However, as fan speed go up they start to perform better but that just means more noise. Generally high FPI radiators perform best with high RPM/static pressure fans, whereas low FPI radiators, such as the Alphacool NexXxos series (~9 FPI), perform very well with a low RPM.

Koolance tends to exaggerate their numbers. A 240 radiator is probably around the vicinity of 100-130w of heat dissipation. I would definitely check out Alphacool, Hardware Labs, XSPC, and EK radiators as they tend to have a better reputation on OCN. I personally have owned an Alphacool radiator of every thickness, they are all well built and work extremely well with Gentle Typhoons. Hardware Labs are among the most well built radiators out of all the listed companies and their SR-1 series (~9 FPI) are as great performers as the Alphacool line.

Thanks for the response, hiarc smile.gif

The reason why I'm looking into the Koolance rads is because as far as I can tell, they have the highest thickness of their given density.

As i stated before, maximum heat dissipation is first and foremost.

I'm looking to pair the rads up with high pressure, high flow fans (40+ dBa), so the noise level isn't too much of a factor.

If someone can convince me not to purchase the rads and/or reccomend some other brands/models it would be greatly appreciated biggrin.gif

Oh wow, I just noticed you want to cool both components with a single 120 radiator, haha, totally overlooked that.

The minimum that you should aim for is a 360 radiator, however a single 120 with good fans MIGHT be able to handle some of the heat load.

Personally, I still think a Monsta/UT60 (120mm version) is a better way to go, if space is not a constraint, they have such great scaling with additional airflow. Check this chart from Martin's, even though they are 360 radiators you can still use the information to see how well they perform and apply to the 120 versions. The HWLabs GTX is a 20 FPI radiator but I doubt 10 more FPI will give it that much of an increase in cooling capacity. The UT60 is able to dissipate 17 more watts even with less FPI. I guess maybe around 1-2 watts less given the ~10mm difference in thickness, but it is still fairly insignificant as the most important aspect is surface area. A Monsta would be about 10-15% more efficient than the UT60.

I still feel like your temps might suffer, but in the end it is totally up to you and experiment if you really want to. Worst case scenario, you can reuse your 120 in a future venture. smile.gif

These rads will be good for what you want as long as they are used in push pull.
A small rad with very high speed fans will give exactly the same result as a bigger rad with low speed fans. The only problem is that as air velocity is increased the rad has less time to exchange heat so efficiency drops off. Densely finned rads will help to reduce that a lot.
I have used the thinner versions of these rads, they are well made and work well if paired with appropriate fans. The thin version is a little more restrictive to water flow than normal because of the narrow tubes used but these new thicker versions should be much better in that regard.
It seems like you plan to use the rad as it has be designed for so I see no reason to not.

Thanks for the responses lads smile.gif

I'm planning to start off by only cooling the CPU, then move onto the GPU.

My case is an Antec 1100, so my rad sizes are limited.

I can install a 120 on the top intake (which will cool CPU) and later down the track a 240 (Once I have removed my hard drive bay).


I have scoured the internet for reviews on this rad, but found nothing mad.gif

I may as well take the leap the faith, what's the worst that could happen, right? I might even be the first person to write a review on them smile.gif as I have no ground for comparison, it can only be positive.
