PrimoChill CTR™ (Compression Tube Reservoir) System Phase II is the latest in a slew of new products that PrimoChill is catering towards the modders and their need for color! What makes the new CTR so unique and not like anything on the market today is the ingenious compression ring end caps that make a watertight seal without the need to cut or tap the end of the reservoir. Similar to the PrimoChill Rigid fittings, the CTR Phase II uses the same principal for securing and sealing off the acrylic tube with little to no force on the tube which prevents cracking. CTRs are the next best thing in the water cooling industry giving the user the flexibility of color as well as sizes to fit their build perfectly.

LAING D5 PUMP
The Enhanced D5 Liquid Cooling 12V Pump Motor – PWM Enabled is the revised version of the popular D5 PWM pump. The Enhanced D5 is still a high reliability, high pressure industrial pump, featuring a 50,000 hour MTBF (5 year lifetime). Such reliability is afforded by the same unique design of the original pump, which contains only one moving part: the magnetically driven spherical impeller spins on a single ceramic bearing, thus extending the life of this pump beyond existing standards. The enhanced part is packed into the new PWM control chip. With this new controller the D5 now has a duty-cycle, feedback, and PWM control that scales in a similar way as the DDC 3.25. This makes it a very reliable and smooth operating pump. This PWM control allows you to automate the pump speed based on CPU temperature using the motherboard PWM CPU fan header. This functionality keeps your pump only running at speeds that are needed. This also allows the safety feature of auto shut down based on RPM feedback if available in your BIOS.
The power for the pump is completely plug-and-play, and connects directly to any computer power-supply through standard 4 pin power connectors and a PWM 4-Pin header. It’s compact design, quiet and powerful motor make it ideally suited for heavy duty cooling in environments where space is at a premium.
