The SilverStone Permafrost PF120, PF240, and PF360 ARGB AIO Coolers Review
by E. Fylladitakis on June 17, 2020 10:00 AM ESTThermal Resistance VS Sound Pressure Level
During our thermal resistance vs. sound pressure level test, we maintain a steady 100W thermal load and assess the overall performance of the coolers by taking multiple temperature and sound pressure level readings within the operating range of the stock cooling fans. The result is a graph that depicts the absolute thermal resistance of the cooler in comparison to the noise generated. For both the sound pressure level and absolute thermal resistance readings, lower figures are better.
In these graphs, we can see where SilverStone’s new Permafrost coolers really stand out. Although the PF 240 and PF 360 do not break any thermal performance records directly, it can be seen that they can offer the same level of thermal performance at a significantly lower level of noise. The PF 360 in particular is almost unaffected by the speed of its fans while these spin above 1200 RPM, with any increase in speed resulting in minuscule thermal performance gains, meaning that the massive cooler can retain most of its performance even if its fans are rotating at half speed. The PF 120 is very different compared to its larger siblings, being unable to match them in terms of performance no matter how quickly the single 120 mm fan spins, but it also cannot ever get too loud, maxing just above 36 dB(A) with the fan at maximum speed.

When will they leak? Had one going for about a decade now, hasn't happened yet. Also, saying they cool equally is just plain wrong.liquid_c - Wednesday, June 17, 2020 - link
You have never used an AIO cooler. Of that, i’m sure.Beaver M. - Saturday, June 20, 2020 - link
You have very bad hearing, of that I am sure.Lord of the Bored - Thursday, June 18, 2020 - link

Some do cool better. But not by much. Maybe 5 C at best. Thats not worth it at all, especially those that can do that are extremely expensive.But they are also louder. The pumps are hard to get silent even in very professionally damped cases, because its a very low frequency hum that vibrates the whole case. Imagine an external 3.5" HDD sitting on your desk.

Well thats short sighted, I moved from a desktop midi tower to an itx case (Old CM Elite 130) which sits the PSU above the cpu and the standard Ryzen 5 1600 cooler was too tall for it to fit.So i either chose a low profile air cooler (which basically couldn't breath which meant no overclock) or replace it with an AIO. The AIO was a much better fit for the job.

When you have a system fully coordinate with RGB , it looks fantastic..so you are missing the point due to lack of knowledge or experience.PeachNCream - Thursday, June 18, 2020 - link
Not sure that's an accurate assumption. People have a variety of tastes in what constitutes something that looks "fantastic" so you will see variance and differing opinions regarding what impact RGB has on a computer. If you enjoy it and feel it is worth the additional software and hardware along with all that comes along with it, then go for it and enjoy yourself. On the other hand, failing to note the possible security problems, additional raw materials investment (and potential environmental damage the extras require - every little bit we conserve of our world helps in some small way) and other ramifications would be irresponsible of us.ritawgoodman12 - Thursday, June 18, 2020 - link
