Anyone have an XP-120 on a Biostar 6100-939?

I'm looking to build a system around a Biostar TForce 6100-939 motherboard. The case I'm looking to use is very small, so I want to get some measurements on the Thermalright XP-120 heatsink before I buy it. This is what I need to know:
  1. When the above motherboard / heatsink combo are together, how far past the top edge of the motherboard does the heatsink extend (disregarding the fan and fan clips)?
  2. What is the vertical distance between the highest heatpipe and the top of the heatsink?
If possible, pictures would be informative. Thanks in advance.
 
I do not think you can ruly hope to fit that monster in anything but a large microatx or bigger you may want to try something with a lower profile maybe like a 1u or 2u all copper solution alternatively you could probably have similar results modding an xp-90

The thing about low-profile heatsinks is that they are too short. A 1U heatsink will certainly fit in the case that I'm using, but it's not ideal; it'd be a huge compromise. The XP-90 is much too tall for what I'm picturing.

I'm limited by only 2 things: height (the dimension outward from the processor) and how far it extends past the closest edge of the motherboard. I already posess the motherboard I'm using, as well as the case. I know how they fit together. There are a few millimeters between the mATX motherboard and the elements of the case which interfere, and a couple / few inches of height between the processor and the interfering element (the power supply).

I'm looking into the XP-120 because it's the shortest heatsink that Thermalright offers. If the measurements work out perfectly (and I mean perfectly, divine intervention could not make things more perfect), I can mount the XP-120 to the motherboard with the processor installed (note: this may involve removing the IHS), and have it so that the heatsink just lines up with the edge of the PSU (which is a ATX power supply with a 120mm fan) so that the PSU's fan is also serving as the heatsink's fan. This might involve trimming some excess heatsink material off the top, which is why I ask how much metal is above the highest heatpipe.

By my estimation, the XP-120 will only extend a couple millimeters past the top edge of the motherboard, which gives it a very close chance of fitting into my case.

Obviously, things are very, very, close. Which is why I'm asking other people if they have this combination installed before I buy anything else. 😉
 
what case are u using? I am using that mobo in qpack type case. Because the case is so small air circulation is a problem(the case is just full of stuff)
I used a Thermatake copper heatsink that had a 92 mm adjustable fan. I replased the 92 with a 80 mm and pot a 3" pvc elbow that draws air from the outside.
Careful about just blowing air inside your case, try to move the air in a specific direction. These picts are not too clear but check them out.

PS I replaced my asus 6150 mobo with this and I am very happy with the Biostar
 
The case is from a Sony Vaio, which is surprisingly well designed. Space for the heatsink is pretty much the only challenge. Here are a couple (big) pics to give a better idea of what I'm talking about:

Top-down view; you can see the small amount of space between the top edge of the motherboard and the CD-ROM drive.

A more angled view, to give an idea of how much height is available.

If I can make the XP-120 fit, I won't need a fan, since the 120mm PSU fan will be right on top of the heatsink. I don't know of any other heatsinks that would work better for this type of setup.
 
Why wouldn't it work? The whole point of the heatpipes is to move the heat from the base to the top fins, where the airflow will be. Tests have shown it doesn't matter which direction the air flows across the fins, so long as the heatsink is directly next to the fan. And it will be.

The heatsink you link to is far too tall anyway. I need something short and wide, not tall and narrow.
 

My mistake I forgot the ps is right in front of the cpu.

there is not gonna be enough airflow. Dont forget the cables drives etc. You wiould need at least a fan blowing across the heatsink.

Try to use a ps that sucks from the back, not the bottom. Than u can use this,

Your original idea is for the ps fan to suck the radaiting heat off the cpu. It may work but I dont think it will work well. Once you add the extra heat in the case it will overheat the cpu.
 
That sort of setup would definitely work (assuming the XP120 fits), however, I'm pretty sure that you would get less than desirable temps and the PSU fan would ramp up. I would use some AMD chip that doesn't produce much heat (Sempron, maybe) and I would also consider replacing the fan in the PSU you're going to use with a higher speed one.
BTW, I have an XP-120, so I'll see if I can PM you the measurements you need in a few minutes. I'm using a K8N-Neo4-F, though, so the CPU socket may not be in the exact same position. (actually, looking at the pics on Newegg, it's about 2 cm lower than the socket on the Biostar board is).
Edit: PM sent.
Edit 2: If you're really worried about the clearance on the sides, you may want to switch the TForce motheboard for an MSI K8NGM2-FID, since it has at least an extra centimeter of clearance between the edge of the retention bracket and the edge of the motherboard.
