TITAN Vanessa Heatpipe CPU Coolers
We made use of a mixed bunch of hardware we gathered to make The Ultimate Steamin’ Hot Test Bed right here at VR-Zone.com. Here’s the specifications:
Pentium 4 Prescott 670 @ 1.36V
2 X 1GB Cosair XMS PRO 3500LL (2GB Dual Channel Kit)
Gigabyte NVIDIA GeForce 6600 DDR2
Antec Truepower 550W
Intel Default Cooler
Titan Vanessa S-Type
Titan Vanessa L-Type
For the purpose of a heatload, we chose Intel’s Pentium 4 Prescott 670, clocked at 3.8GHz with a whopping 2MB of L2 cache. Possibly one of the hottest single core CPU of today, we shall make sure that the Titans put up a good fight against the heat produced by the Prescott, thereby keeping things cool and stable.
Temperature readings were taken off the ITE IT8712F device on the Sapphire 17RS400 via SpeedFan 4.25. For the purpose of this test, the internal temperature diode of the 670 proved most capable of discerning minor temperature differences, being affected neither by the mounting position/pressure of an external temperature probe nor the probe’s local heat capacity.
To load the Intel Pentium 4 670 (both the main CPU and the logical HT core), we ran an instance of Prime95 (in-place large FFTs for maximum heat, power consumption) along with 32M Super Pi calculation. The 100% CPU loading lasts for 20 minutes after initiation. The highest temperature detected by SpeedFan 4.25 is defined the load temperature.

- Idle temperatures were recorded 20 minutes after the setup booted into Windows XP SP2. The highest temperature detected after the idle period without load is defined the idle temperature.
- C1E (a power saving feature acquainted with SpeedStep and akin to Cool”n”Quiet by AMD) was blatantly disabled in the BIOS to ensure the Intel Pentium 4 670 maintains a constant heat output.
