ID-Cooling Frostflow 240L Closed-Loop CPU Cooler Review

Test Results & Conclusion

Comparison CPU Coolers

We use the hardware configuration from previous reviews to make all of our results comparable. Here's how the Frostflow 240L's specifications compare to other 2x 120mm closed-loop coolers:

Test Results

The Frostflow 240L keeps our overclocked Core i7-5930K supremely cool inside Corsair's Graphite 760T, even after an extended warm up at full load. The voltage regulator (PWM) of MSI's X99S XPower-AC also reaps some of the benefit of the nearby high-flow fans.

High airflow doesn't always require high RPM, as the Frostflow 240L's eleven blades are highly curved to produce more pressure. There's usually a trade-off in noise, so let's check that out!

The Frostflow 240L is noisier than Swiftech's H220-X, but far quieter than the Gamer Storm Captain 240. When I looked back at some Big Air numbers, it's still noisier than any of those coolers. Then again, it's cool enough to run this system fully-loaded at minimum (50 percent) fan settings, and 27 decibels in open air becomes whisper-quiet when the case is closed.

The Frostflow 240L's best possible temperatures, combined with better-than-average noise levels, produce a 3 percent above-average acoustic efficiency at full fan speed. Highly-curved fans tend to operate more efficiently at lower RPMs though, and that's where we find the Frostflow 240L leading all competitors by a huge margin.

The only other "acoustically efficient" cooler in this comparison is Swiftech's H220-X, which comes at a far higher price than ID-Cooling's Frostflow 240L. That allows the Frostflow 240L a large margin in value, beating the average of all liquid coolers by 32 percent (price-to-performance) at full speed and 98 percent at low speed.

Our test results speak for themselves. ID-Cooling's Frostflow 240L offers the best full-speed temperature ever achieved on this test system, the best low-speed acoustic efficiency of any closed-loop cooler tested on this system, and the lowest price of any 2x 120mm cooler ever tested on our system. However, while some users prefer integrated fan and pump control, the Frostflow 240L uses motherboard-based controls.

ID-Cooling pushes the value envelope by selling its product directly to customers at the lowest-possible price, undercutting competitors by an average of 22 percent. Fan blades designed to operate efficiently at a fairly low RPM are paired with a medium RPM fan motor, so users are best to leave fan control up to their motherboard. Better performance at a better price make the Frostflow 240L this editor's choice among 2x 120mm closed-loop CPU coolers.

    Well, it would be nice if we could buy this, but it is no longer available at the link provided.

    id-cooling is selling these directly from the factory through an eBay store: http://www.ebay.com/itm/181842957385

    Thanks

    Now as for the article, I kind of like the simple solution of having the motherboard control the fans, but understand that some may want a more robust solution. Very good article.
  • cknobman
    This looks impressive for the price.

    Probably my first choice (for the time being) when I upgrade (or do a new) my gaming rig build this year.

    This is an excellent piece of hardware. I have the Corsair H100i now and the software controlled fans are extremely buggy. I'd love to be able to control everything with the motherboard.. Definitely my next buy if they prove to be reliable.
  • gilbadon
    Yay, do more aliexpress reviews! I love all my Chinese stuff. ID_Cooling makes some great radiator fans. For $8 a pop on newegg they pack a bigger punch than most of corsair's lineup.
  • ykki
    Great! About time we saw some new cpu coolers that actually disrupt the current recommended lineup.
  • SuperVeloce
    I don't understand why motherboard fan control qualifies as a "con" in 2016. When you get a picture of the temperature range from your cpu under this cooler, you go to UEFI and set an appropriate custom/auto PWM curve for your needs. Then you just forget about it.

    I think the original said "motherboard only" and it's only listed as a "con" because it's a cost-offset. The article clearly states my preference for it.

    I'm up for any re-phrasing ideas in the pros and cons box. Getting it changed could take a day though because the list is in a graphic that I can't access.

    Okay, so this is the coolest thing I have seen in weeks (and CES just happened!)

    Yeah, I'm liking the results, but I'm wary of chinese engineering. I know most companies, regardless of brand, are manufacturing their products overseas, but when it's designed there as well, those kinds of products tend to start showing issues after a while. I'd like to wait a while before recommending this and see if trends regarding component failure or leakage become prevalent.

    Even their website, when you click on "English" below thermal solutions, is broken, and shows you a Chinese version. I'm pretty sure all those chinese engineered hover boards catching on fire was just a fluke though. Hopefully, this IS a decent product and I'm wrong about the quality, as it wouldn't be the worst thing in the world for some of the better known brands to have to up their game a bit.

    Maybe the link is taking you to the wrong place? How about starting out from the English-language website?

    Yeah, that link definitely works better. Not sure why Google isn't offering that up as a primary link instead of the one I was seeing. Thanks Crash.

    Great liquid cooler but the stock fans creates echoe vibration sound at loud rpm. Overall great budget aio
  • Darkbreeze
    I still don't see any of these for sale anywhere in the US, UK, Deutschland, Canada, Australia, Italy, Spain or New Zealand, any of the places our user base tends to originate, and PCPartpicker represents, so did they decide not to sell these or are they only going to be available for sale to people in Asia?

    Not even sure why they sent you a review sample if they didn't plan to bring them to market anywhere.

    They sell them direct.

    I see. Ok, thanks for that info. Much appreciated.

    Have you used the sample for any length of time since doing the review and can you offer an opinion on whether there are any concerns that may have cropped up since the initial review. I may want one of these for a client build if they're a solid product. I know a lot of products look good initially, and then problems present after a while so I'm just interested in knowing if you'd seen anything you'd be concerned about.
  • Darkbreeze
    And are they warranted through any US locations, or do they have to be sent overseas if there is a problem?

    I'll tell you what: I can't say much about what to do in a pump failure (I'd hate to send the whole unit to China), but in the event of a fan failure tell them you know me :D
  • Darkbreeze
    Ok boss. Thanks.
