EK CoolStream Radiator XT 360 (120.3)

Quality at EK level and an optimal price-performance ratio make these EK-CoolStream RAD XT radiators unique. The new radiators feature, besides their great design and high build quality, great cooling performance. The copper fins are specially designed for Ultra-silent fans (with low Airflow). The parallel coolant channels reduce flow resistance to a minimum. On both sides of the radiator the M3 threads are integrated to allow fan installation on both sides and radiator mounting. The radiator has integrated G1/4" threads, allowing installation of virtually all common fittings. Please note: Over-tightening of the screws may damage the radiator. Always take care that the screws do not damage the radiator. Damages of the product because of improper use are not covered by the warranty!

Technical details:
- Material: Copper fins, Brass chambers
- Dimensions (LxWxH): 398x123x47mm
- Connection threads: G1/4"
- Weight: Approx. 1350g
- Fan installation: 12 x M3 threads on both sides each (for 3x120mm fan each)

struggling to cool haswlel i7

Decent radiator, excellent price. Although fully delided i7, not overclocked reached around 50 celcius. Radiator struggles to cool down the water after running prime for 1 hour. Using Corsair silent 1450 RPM fans. I had better results with 240 mm rad.

Just my experience. Users below seem to have it working just well.


Very Good Rad for SLI Only

Was unsure if this Rad was up to the job for cooling 2 GTX 580's in SLI, Previous load temps were above 80c, now they dont pass 58c, great buy. I have my proccessor on a separate closed loop & dont think this rad could handle more than a CPU/GPU or SLI GPU set up.

Brilliant product for the price

Bought one of these and finished set up of rig yesterday. Left the thing running all night and can report great temps cooling 2 Asus Nvidia 470's in SLI. They peaked at 37 degrees idle and only get up to 58 when running vantage(p). Using EK waterblocks, XPSC res/pump combo and 3/8 tubing. Beat all my expectations and now my neighbours cant hear my 470s when I am playing Empire total war.
