Time to find out how well does the Nemesis GTS 240 perform.
Our testing methodology:
To measure pressure drop across the block I use the Dwyer Series 477 Manometer. The pumping power was provided using a Koolance D5 strong and the flow was measure using a Koolance INS-FM17N.
For thermal testing I use the following:
- Motherboard – Gigabyte Z87 OC
- CPU – I7 4770K
- Memory – 4 GB GSKILL Trident
- CPU Block – EK Supremacy
- Data Logging/Fan Control – Aqua Computer Aquaero 6
- Coolant – Distilled Water
- Fans – Gentle Typhoon AP-15 in push only.
- Stress Testing – AIDA 64
The new Nemesis GTS 240 has a lower flow restriction when compared to the old Stealth GTS 240.
When reviewing a radiator I like to run the stress tests at different fan speeds to see how the radiator performs at those speeds. Once you run the fan above 1400 RPM the radiator really shines. Above we see CPU temps at different fan speeds.
While collecting CPU temps, I also collect the Delta T temps. Above we can see what Delta T temps we get for different fan speeds. Based on the above you start getting diminishing returns once you start going over 1600 RPM. I like radiators that work great at low RPM fans making for a nice quiet build.
Finally here are some numbers that compare the new Nemesis GTS 240 to the old Stealth GTS 240. As you can see the the Nemesis GTS 240 gives up on performance a little to maintaining a lowered pressure drop across different flow rates. The old Stealth GTS 240 does a better job as the load increases but not with a huge margin.
