Watercool HTSF2 3×120 LT 360 Radiator Review

Push Performance – 3.5/5

Push/Pull Performance – 2.5/5

Overall Performance – 3/5

The HTSF2 is too biased towards low fan speed setups to perform well overall.  However it’s average performance was still respectable as the radiator still scales quite well with higher airflow.

The restriction level was high so installing multiple HTSF2 radiators in a loop would require adequate pump power, especially as the thermal results were worse with lower flow rates.

Features & Quality – 4/5

The Watercool HTSF2 has the best finish of all the radiators in the test group. The polished stainless steel end tanks and powder coated side panels give it a distinctive and stylish look. The core was well constructed with even fin placement down the tubes on the finned tube style core.

The fitting of the ports was the only let down as they were not fitted squarely and pointed out at an unusual and unsightly angle. The design meant that the ports protrude a significant amount from the radiator housing.

Due to the core design and coolant flow path, alternative inlet/outlet ports are not fitted, nor is a bleeder/fill port at the return end.  The hex pass design also means that coolant will be exceptionally hard to drain out.

Summary – 3.5/5

The Watercool HTSF2 LT is a premium priced radiator being the most expensive by far in the test group. For that money you get precision German engineering and European manufacturing which oozes style and not some stamped out made in China clone. Unfortunately the core design, stylish as it is, does not translate to great thermal performance. It is a restrictive radiator also. Relative performance may improve in push or pull only fans, but with push&pull fans as tested, the HTSF2 fell short of the mark on performance.
