Air doesn't move if you have it off.
Below is my other rig which may show it better. You can see the top and side fans. The top blows out because heat rises and you can see the side fan blows cool air right into the Zalman. A 100cfm fan in the front and back so air
is being moved well.
Maybe it's just the pic but it took me a little more AS5 to cover my processor. I was suprized you were able to lap it flat without hitting the copper. Must not have been that big of a crown then. I just had a little silver left on top when I was done with mine.
We will get this figured out and you are learning a lot in the process. Hope you enjoy it as much as I do.
I am stubborn if nothing else. In my 70 years I have had a stroke, carotid artery surgery, open heart sugery, a heart valve replaced and a by-pass and I'm still up and around and going to the gym 3 times a week. I don't give up easily.
-I'm finding that ambient temps make a big difference, and yes all measurements are with the side cover on.
-I am running Orthos blended CPU/RAM at 100% full chat. Room temp right now is about 24*C, temp inside the case is about 26/27*C, mobo temp is 35*C and cpu is 52*C and holding steady. The 2 hard drives are running 34/35*C respectively.
-Our rigs are not that much different. Mine is a little more compact. Both my side fans blow in, the upper one has a speed controller on it so that I can set it to blow enough air to pressurize the case and force air out the vent on the other side of the case. Fast or slow speed, the CPU temp stays the same and it sits almost on top of the Zalman. The front fan also blows in with pretty good volume. Remember the inside case temp is only about 80*F.
-I found my chip did have a crown in the center, but it also had a slight ridge
on either side, so I lapped it with 1000 grit water sandpaper, and polished it with red buffing compound. Did the same with the Zalman, but it was pretty good to start with. Actually, the stock cooler had a pronounce bulge on it, readily seen with a straight edge. Funny thing is, The Zalman is not a lot better than the stock cooler.
-Eventually I will pull the cooler back off and check how good the AS5 coverage is. The Zalman is not hard to install, but it is almost impossible to keep it steady when starting the screws, it will move around a bit. Dunno if that is detrimental or not. We shall see.
I really appreciate the way you have helped me with this, I have learned a lot and loved every minute of it. I've been working on computers for a long time, back when PC's didn't even have hard drives, but back then heat wasn't a problem, there wasn't even a fan on the cpu, just in the power supply.
