Enermax ETS-T40Fit CPU Cooler Review: A Twist on a Classic
A Closer Look at the Enermax ETS-T40fit
As far as tower-style heatsinks go, the ETS-T40fit is rather modestly sized, measuring 126mm wide with a thickness of only 42.5mm without any fan installed (67.9mm with fan). Every single surface of the ETS-T40F-BK with the exception of the contact surface has black thermal conductive coating. The finish is non-reflective and not thoroughly glossy but it is a smooth and surprisingly thick coat, making the Enermax logo and airflow arrow label at the top barely visible unless closely inspected. From the top view, angled perforations are visible near the heatpipes that allow for air to pass between each level top to bottom. Every single aluminum fin of the 52-piece set has these.
Four 6mm heatpipes form a U-shaped design distributing heat to the aluminum fins. These heatpipes are arranged so that the first and third heatpipe form a closer “U” shape while the second and fourth heatpipe form the outer “U” bends. The fin design is open on the wide surface while the center of the sides are closed. The aluminum fin array design is partitioned into thirds with the middle third sloping flat while the outer thirds have outward angled serrations.
The base has fully exposed copper heatpipes that have a rough brush machined finish with gaps between them formed from the aluminum base. Total contact surface area measures 42 x 38.2 mm.
The fan installs on the ETS-T40fit using plastic retention mounts that have to be screwed in place. The bundled fan is already attached to the retention mounts and has the rubber pad with adhesive backing that dampen the noise.
The bundled fan is a blue LED Enermax Twister Bearing Apollish fan with sleeved PWM connectors. Twister bearing is essentially a magnetic ball-bearing design that runs much quieter and has longer life than standard ball-bearing or rifle-bearing solutions. There are seven blades in total which have a hint of blue transluscent hue that accentuates the 9-LEDs that fireup once the fan is running.
These LEDs are extremely bright for such small diodes and when the the fan is on, the light fires through the fan curve creating a cool twister effect.
The fan cable is nicely sleeved and has a 4-pin connector, Readings from ASUS Fan Xpert II reveal the real-world controllable PWM range:
