The SilverStone Permafrost PF120, PF240, and PF360 ARGB AIO Coolers Review
by E. Fylladitakis on June 17, 2020 10:00 AM ESTTesting Results, Maximum Fan Speed
Our maximum speed testing is performed with both the fans and the pump of the kit powered via a 12V DC source. This input voltage should have the pump and fans matching the speed ratings of the manufacturer. As per SilverStone’s specifications, the fans should have a rotational speed of 2200 RPM. According to our tachometer, the speed of the fans is spot-on at 2200 RPM. Furthermore, the speed difference between the six fans we tested was negligible, indicating great manufacturing quality and minimal deviations.

A glance at the average thermal performance charts reveals that the new SilverStone Permafrost coolers perform as expected of their size and technology. Their raw performance falls very close to that of similarly sized coolers, outperforming some and losing to others. The average thermal resistance of 0.0732 °C/W that the PF360 achieves is remarkable for any kind of CPU cooler, yet it does not break any records and is overshadowed by the impressive 0.0773 °C/W figure that the PF240 achieved. The smaller PF120 has a substantial performance gap compared to its larger counterparts but does perform well for a single 120 mm AIO cooler.
In terms of acoustics, SilverStone’s engineers did an excellent job. Despite that the fans supplied with the Permafrost coolers are relatively high-speed, the sound pressure levels of all three coolers are comparatively low. As a result, the larger coolers end up outperforming models that use one or even two fewer fans.

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
