Inno3D introduces the WAVE for passive cooling solutions

Hong Kong 28th February, 2007 – InnoVISION Multimedia Limited introduce the Wave for passive cooling solutions to their Inno3D® mainstream 7 series. It is the best solution for not only system integrators but also professional graphic designers who like to work in a quiet environment.


The main advantage for passive cooling is that it generates zero noise whilst continuously cooling your area of your graphics card. As shown in the below table the comparison between passive cooling and active cooling, you can see that the cooling performance is both effective and stable.



The main features for the Inno3D® Wave design include:

1. Curve Wave design – is uniquely designed to penetrate heat from top to bottom of the PCB and also circulates heat in and out. (Refer to the diagram)

2. Clipping Arm – is clipped securely onto the top part of the PCB in order to help absorb heat (Refer to the diagram)

3. Double sided Aluminum Extrusion Fins – increases surface area consecutively to radiate heat efficiently (Refer to the diagram)

4. Raise specific heat capacity – lowers temperature increment i.e. is the measure of the heat energy required to raise the temperature of a specific quantity of a substance by a certain amount.



The Inno3D® Wave is the perfect solution for silent cooling. It is ready and equipped to the mainstream 7 series. For more information for passive cooling solutions please visit Inno3d.com or contact our sales representative.Source: Inno3D

This would work well in SFF or HTPCs but I dont see it being used for the heavy hitters. Perhaps the lower end to lower mid range cards at best. Unique design though.

That's a very clever design... looks cool too. (sic).

Issues:
1./ "Penetrate"? I don't want heat penetrating ANY of my devices TY.

2./ Clipping design is good for a secure mount. But to "absorb heat" from the PCB? That's BS. The heatsink is going to be HOTTER than the PCB due to mounting over the GPU/RAM. Therefore it's going to transfer heat TO the PCB. While this is probably not a problem... the marketing PR is pure BS

3./ I don't want double sided fins. I want ZERO heat being radiated BACK at the PCB. Dumb. Real dumb.

4./ Raise specific heat capacity – lowers temperature increment How is that of any benefit at all? A GPU is on, not for minutes, but for hours. I don't care how QUICKLY it gets hot, but the MAXIMUM temperature and cooling efficiency.

THERE IS NO WAY the chart shown above is accurate. It doesn't take card 30 minutes to warm up. Unless, its sitting there, idle. The graph should show temperature UNDER LOAD.

Notice how at 65C the fan cuts in on the active cooler... and starts cooling the GPU. But on the passive it just keeps getting hotter and hotter. But wait... HOW ON EARTH CAN A PASSIVE COOLER start cooling faster (see 40 mins). This chart is BOGUS.

IMO "The Wave" should be a lot bigger... extending beyond the end of the card to provide "more thermal capacity" and "more surface area" for cooling. It should also ONLY be used on medium or low power GPU's.
