Final Thoughts

The Koolance PC4-1025 combines an advanced liquid cooling system with an elegant enclosure that is sure to please even the most demanding enthusiast.  You will be hard pressed to build a more capable system from scratch.  The PC4-1025 Liquid Cooling System delivers excellent performance, advanced features, and modern styling in a self-contained and easy to install system.  The finished result looks awesome and presents a professional appearance!

Please keep in mind though, that along with all the benefits that water-cooling offers, it also adds complexity and can make a typical system more difficult to work on, especially if you like to constantly tinker and change hardware.  For example: having to clear the CMOS is a fairly common task that many overclockers encounter.  When I had to do this on the PC4-1025 system, at first I couldn’t even see the battery or CLRTC jumper, let alone get to them!  But once again, thanks to the PC4-1025’s slick design, removing the fan/radiator assembly from the top of the case provided the necessary access.


Note: If you’re looking for a larger enclosure, Koolance also offers the same PC4 liquid cooling system in two larger case styles: the PC4-1026 (deeper PC-V1200 chassis) or the PC4-1036 (taller and deeper PC-V2000 chassis).  Both of these larger cases will accommodate a longer power supply and provide additional internal drive bays.

Outstanding style, function and performance come at a price however.  In the case of the Koolance PC4-1025, that translates to a MSRP of $599.99 USD, which does not include the waterblock coolers.  The PC4-1025 is available in silver or black from your favorite Koolance reseller.  And finally, I would like to thank our friends at Koolance for sending us the PC4-1025BK to review (and for their patience 🙂  Thank you!
