The second HIS variation on the Radeon HD 4670 theme has an active IceQ cooler, which glows blue under ultraviolet light (check the gallery to see this feature in action). Because of the fan housing, this card is two slots wide. The fan and housing circulate air through a channel that picks up heat radiated from the heatsink’s cooling fins and blows it out of your chassis through slots in the front of the card. The Radeon HD 4670 is an efficient and cool GPU that runs fairly quiet at 36.5 dB(A). Even under heavy 3D loads, the fan doesn’t run at high speeds—according to GPU-Z, it stays at a steady 30% of its maximum rotation.

As is typical for HIS, clock rates are slightly elevated on the H467QT512P—the GPU runs at 780 MHz instead of 750 MHz, with the memory clock at the standard 1,000 MHz. The overclocked GPU provides a modest bump to overall performance of about 1.3% (measured in FPS). The clock speed boost comes from a BIOS setting and operates independently of the graphics driver version in use. Its 320 stream processors (SPs) support DirectX 10.1 and Shader 4.0, and the card’s 512 MB of GDDR3 RAM are enough to offer playable speed in some games, even at 1920x1200.

This card clocks all the way down to 165/250 MHz (GPU/RAM) in 2D mode. The retail package omits video cables, and, like the previous board, no power adapter is necessary because the Radeon HD 4670 gets all the power it needs from the PCIe bus. A DVI adapter makes HDMI available, and the card is 7.5" (19 cm) long, including the fan housing. The quiet IceQ cooler improves noticeably upon the Radeon HD 4670 reference design, and helps enable a fairly differentiated product.
