Direction of Heatpipes with TT Big Typhoon VX?

I purchased a TT Big Typhoon VX for my E4400 and have been pleased so far. Using my Abit AW9D my idle/load temps were 38/56C using Orthos CPU stress. I have since replaced my Abit with a MSI P6N SLI Platinum. My idle load temps are now 42/64C, which seem rather high compared to the Abit. I have been using CoreTemp 0.95 to measure the temps. My question is should the heatpipes on the BT be oriented horizontally or vertically? I have mine oriented horizontally at the moment with the fan blowing down. I have sieen it mounted in both directions in various google searches, and I didn't know if this could be the cause of my large difference in temps. Could a bad application of thermal paste be the problem? I have to remove the motherboard to reinstall this heastink since I can't reach the back screw, so I only want to do it once.
 
Does your hsf have any documentation that you can view? I'm about to mount an enzotech ultra-x on the same mb as you and the documentation shows the pipes going to the side towards the ram. I've seen them mounted all different ways but I was thinking that since heat rises that the pipes should be on the top of the cpu pointed up towards the ps since that is how it will sit in the case. Also how much thermal compound did you use and how did you orient it on the cpu? AS shows to make a single line following the cpu as it sits under the heat spreader. This is what I did with the stock hsf after I removed it the first time. I tried using a tt tmg-i1 and the feet wouldn't lock into the mounting holes right so I had to rma it which is why I've got the enzotech unit coming tomorrow.
 
Heatpipes orientation is irrelevant.

The temp difference you have can easily be attributed to a difference in the mount. If you're using different mounting clips on this board, then that right there could be the whole thing.
 
Did you check the thumb screws to make sure that the base is even with the top of the cpu? I don't know how it mounts to the mb but most of the ones I've seen are more secure with a 775 mount than with the amd versions.

I used a straight line, as the AS5 directions indicated; however I'm using Artic Cooling MX-1 Paste. I have found it to last longer and the temps to be the same as AS-5, only cheaper. I think that I might try it with the heatpipes mounted upwards just for kicks.

I am using the same mounting system as I did on the Abit board, both are 775 MBs.
 
couldn't it just be a case of two different motherboards with different bioses (award/ami) reporting two different sets of temps rather than a faulty hs/f installation?

Heatpipe orientation does matter for the Big Typhoon. Let me clarify, fin orientation mattes and I think that's what the OP meant. He was using the heatpipes as the reference point. Remember the fins are vertical so if you orient the fins aligned with the flow of exhaust fan, the exhaust fan will help cool. If the fins are perpendicular then there's an obstruction. This would matter more when running fan undervolted or low RPM fans. At high speeds the side effect would probably not be noticeable, certainly not 8C difference as the OP is seeing.
 
You might have used too much thermal grease. I used a slightly larger than a grain of rice blob in the middle of the cpu then worked it around just a little before I mounted the hsf down. My temps are fantastic with the ultra-x and I did mount it with the heatpipes facing the ram just like the instructions showed.
