I took the 4870 back out of my machine tonight to get a closer look and the board and the discrepancy between it and the 4890. The components on my board are not missing any kind of heat sink material. They are fundamentally different from the four below them. So thats somewhat of a relief.

I also decided that even though having a cool CPU is nice… blowing large amounts of sub-zero air into my office was not. I went ahead and used the box the system came in, and made a nice fitting box for the fan set. I then reversed the top fan again, so the bottom sucks in cool air, then the top fan blows it back out. It raised the temps on the water system by about 10 degrees… but it also did the same for my office lol. I can live with mid 20’s idle, and low 40’s under load.

I’ve been going back and forth with Frozen CPU trying to see if I could get a return exchange on this block… we’ll see what happens. The good news it that they carry a block that looks like a perfect fit! If I can get a credit from them, I should be able to get it next week.

Also, I think I may have found a portion of my cooling issues on this card. If you take a look at these photos:

You can see on the right that two of the power supply transistors are missing their heat sinks. I never really thought about it until I saw a reference image for the 4890. I’ll have to see if I can get that corrected before tonights raids 🙂
