Bykski's New External Cooler Could Be Bigger than Your Desktop

If you have several different GPUs or a very compact case with weak airflow, you can take your cooling to the next level by getting a giant cooler that sits outside of your case in its own box. Cooling specialist Bykski has introduced a huge external cooler to cater for your extreme cooling needs. The new Bykski B-1080-CEC-X “external cold exhaust heat dissipation chassis” features a 3x3 array of 120mm fans, with integrated pump, radiator and reservoir for easy plumb-and-go (G1/4) fitting to liquid cooling loops.

This unit measures 419 (H) x 488 (D) x 138mm (W) so looks like a typical mid-tower chassis but a little slimmer, but would overshadow a compact mini-ATX system. Twitter’s Momomo_us spotted this cooler listed at Y72,356 before tax in Japan, which is about $525 today.

Suggested uses of the Bykski B-1080-CEC-X are the following:

  • Server cooling,
  • High-end gaming systems,
  • Compact computer systems with up to 4x GPUs,
  • And for compact powerful systems which don’t have the internal space for a water cooling radiator.

In some of the above use-cases the B-1080-CEC-X might be overkill and a more modest external solution like a Bykski Granzon G10, or Bykski External 360mm radiator stand might be better, cheaper options (if you already have a radiator that doesn’t fit in your case, for example).

Whichever application you use this 9x120mm external cooler for, it is claimed to be capable of handling up to 2,000W of heat dissipation. That is plenty for a gaming system combining the most power hungry components popular with consumers right now, like the Core i9-13900K and GeForce RTX 4090 (250W+ and 600W+) running at full pelt. Like we said above, the B-1080-CEC-X might be overkill. However, perhaps it can run extremely quietly with lower thermal loads – slower RPM etc.

In addition to the support for 9x 120mm fans, the chunky B-1080-CEC-X bx contains a 46mm thick radiator made using a mix of copper and brass – with 30 double water flow channels. The integrated pump offers a water flow of up to 700 liters per minute, tested at up to 1.5bar, and connects with water loops using the popular G1/4 tubing.

Looking at the fully built unit from the outside; there is a water level gauge on the front panel, significant venting both sides, around the back are both the fluid I/O connectors and power input (connecting to a 4-pin Molex HDD from your PC), as well as a water injection port atop of the case for top-ups.

    Why?

    Just buy a more suitable case.

    I think it's a cool product. like the zalman reserator, but this time without the aluminum hopefully.

    2 small cases with Quick disconnects can be easier to manage than a bulky case. I know what im talking about just check my signature lol. my tower is as big as a furniture, and it takes 2 people to move it with all the rads inside.

    Doesn't matter how big a case is or how well ventilated it is, external radiators will always breathe better. My external 560mm radiator performs about as well as my S8 with 23 x 120mm fans worth of rads and my Entoo Elite with 16 x 140mm fans worth of rads. Both of those cases are basically impossible to move without draining and partially disassembling the loop and even then it takes 2 people to move. An external loop is way easier to transport.

    Oh yes I do. I almost bought one back in the day to cool my OC 6600. I bought a Coolit Systems Freeze zone peltier enhanced water cooler. That did the job I could cool that beast to a few degrees below ambient. It had 3 petiers on my unit. The pump eventually failed and they are no longer made.

    No they are copying the idea of Watercool MO-RA3 360 PRO, but basing it on
    Alphacool NexXxoS XT45 Full Copper 1080mm Nova Radiatorbut adding a D5 pump and rez. More China junk whose IP is stolen from others. Buy the real deal.

    People remember Zalman's Reserator but forget Innovatek to say nothing of the AquaComputer airplex GIGANT which you can actually buy today. Now that's a real tower of power! Seriously though folks just get a MO-RA3.
