Stability Test: The Hydrocool200 Meets Overclocking
In order to see how powerful and stable the Hydrocool200 would be in an overclocked system, we let the cooling setup run for several days in an overclocked Pentium 4 system. The Seti client made sure that the CPU remained maxed out. We measured the die temperature in this stress test using the AsusProbe tool (Ver. 2.20.02) that comes with the motherboard (Asus P4C800 Rev:1.03).
We also ran the very same test with
- the original 3 GHz Pentium 4 boxed cooler,
- Zalman's top-shelf P4 cooler CNPS7000-Cu, and
- the Innovaset R3M water cooling system from Innovatek.
A Brief Run-Down Of The Opponents
The original boxed cooler for the 3.0 GHz Pentium 4 is based on the classic design.
The aluminum heat sink looks like a turbine bucket. It has a copper core to quickly distribute heat throughout the heat sink.
The fan on the boxed cooler spins at 2500 rpm, generating a noise level of 44.3 dB(A) (measured at 50 cm above the fan; ambient sound level 31 dB(A)). But once the cooler has been mounted in the case, you hardly hear any noise at all.
