Close to sixteen years ago, EVGA announced its first “ACS” (Asymmetric Cooling System) cooler for GeForce4 graphics cards. By today’s standards, the cooler was unbelievably simple, but at the time, it introduced the blower-style fan to increase cooling efficiency. One such card to utilize this cooler was the GeForce4 MX 440, an NV17-based GPU built on a 150nm process, bundling in two pixel pipelines and 128MB of DDR.
Barely a month after that card released in February, 2002, EVGA ushered in the ACS2, which was being strapped to the GeForce4 Ti 4600. ACS2 iterated on the original by adding memory coverage, as well as another industry first: heatpipes. While the blower fan on the MX 440 may not have been entirely necessary (passive versions of the card were made available at the time), a more than doubling of performance on a chip like the Ti 4600 could warrant the extra cooling help.
And speaking of help, this is where you may be able to come in. EVGA is looking for a total of 3 cards each of the previous two mentioned, with these part numbers qualifying:
- ACS Part Numbers
- 064-A4-NV70-5K
- 064-A4-NV70-A1
- 064-A4-NV70-A2
- 064-A4-NV70-S1
- 064-A4-NV70-S2
- 128-A4-NV71-S1
- ACS2 Part Numbers
- 128-A4-NV83-A1
- 128-A4-NV83-S1
- 128-A4-NV83-S3
- 128-A8-NV85-BX
- 128-A8-NV85-R1
If you think you have one of these cards, you need to act quick, since EVGA only needs a few of each. If you do have a card, and EVGA agrees to purchase, you’ll be given 1,000 EVGA Bucks, which is in effect $1,000 USD that can be spent on its webstore – perfect for going all-out on a top-end GPU, or upgrading more than one of your PCs to faster GeForces.
Good luck in your hunt!
