Jonsbo PISA A5 Overview
The Jonsbo PISA A5 is not the largest CPU cooler, it has official dimensions of 120 mm(L) x 75mm(W) x 153mm(H). We received the Grey version of the cooler that comes with a grey fan and has a matching grey top on the heatsink. Jonsbo will also be offering the cooler in a white version which has a white fan and matching white top on the heatsink.
Starting at the front of the cooler we have the 120 mm cooling fan. This PWM fan will spin between 800 – 1500 RPM with a max airflow of 81.27CFM, max air pressure of 2.23mmH2O, and max noise level of 36.8dBA. The fan has a grey frame with the fins being an opaque white which is going to go well with the RGB lighting. Each corner of the fan has rubber on it to cut down on vibration noise.
Looking at the cooler from the side we can see just how thin not only the heatsink is, but also the entire package. Being this thin you are going to have 100% RAM compatibility. The cooling fan is held into place by fan clips.
At the back of the cooler we can get a better look at the heatsink stack and how it is all designed. We can also see how the heatpipes go up into the heatsink stack. The top of the cooler is capped off with a plastic cap with the Jonsbo logo on it.
There are five 6mm-thick nickel-plated copper heatpipes that come up from the base of the cooler and go into the heatink in a “U” fashion which is quite standard when it comes to tower coolers. The base of the cooler itself is actually fashioned as a heatsink as well, which will definitely help out with cooling.
You will find pre-applied thermal paste on the bottom of the cooler. Some people may not like this, but I think it is great for first-time builders as applying thermal paste is one of the more daunting tasks for someone who’s never done it before. Don’t worry though Jonsbo does provide extra thermal paste. It is hard to see but this cooler uses a direct-touch design, meaning that the heatpipes will make direct contact with your CPU once installed.
