Does it matter which way round a CPU block is mounted?

Heres how I've mounted my DTek block. The inlet and outlet are connected to the right sockets on the block, I've just chosen to mount the block upside down to aid cable routing. Does this have an adverse effect on temps?

Assuming as you say you've connected the inlet to the center. If its vertical you're supposed to mount it with the outlet above the inlet to help in bleeding the air out. Once its bled it can't make any difference. Never tested it though, given high flow I doubt its really an issue.

Yes it does make a difference. The inlet needs to be in the centre for an even spread across the cores with the outlet situated above, either right or left.
 
So W3bbo is saying yes it does make a difference and fornowagain says it doesnt, and both are experienced in water cooling lol. Who to believe?:confused:

My loops fully bled so that isnt the issue, I just wanna know definitively if orientation will affect the temps on a dual core. Sorry to sound like a stuck record.
 
it does make a difference, but how much of one depends on the block design.

Not entirely sure how much of one on the fuzion, but the cores are aligned vertically when looking at the board straight on in an atx case....so think about that and how the water will move through the block.

I haven't even assembled my water cooling set up yet but it seems fairly clear to me that the only possible factor which could affect the cooling performance of the block is if there is any air trapped in it. If you say you are sure it is fully bled then rotating it will make naff all difference.
 
Technically this is a graphics card question but since my gpu is water-cooled I'm posting it here in the hope of some more sensible advice.

After a few mins gaming this often happens. Card is running at stock but it also happens while overclocked. Tried reinstalling old and new drivers but still happens. It passes any benchmark test without a hitch including Furmark stability test but it always happens while gaming after just a few minutes.

i'd want the inlet going onto the centre

also, some blocks have 'diamond' shaped grooves in the copper, you want to go with them, not into them.. (they come with warnings) -eg apogee

Spot on - Here's some shots of the Diamond Matrix on my Apogee GTZ from swiftech's website:

There's a definte right and wrong way to mount it due to, as mentioned here, on the design of the block.

According to your manufacturer's data:

Again, correct me if I'm wrong, but unless the pin or diamond channel arrangement is somehow asymmetrical, such that should be oriented to align with the 2 separate physical cores in a quad core chip, the direction of water flow to the outlet does not matter. I think with the DTek fusion, if you take the top off the block, the block is symmetrical in both planes, i.e. rotate it and it will look the same. With a single physical core chip in the middle of the heatspreader, i.e. core2duo, with the inlet in the middle it should therefore not matter where the outlet is. To my mind the only thing to be wary of is if you use a nozzle. That should be aligned to where the physical cores are, but again the location of the outlet barb will make sod all difference imo. Of course, when fitting the nozzle you have to take the top off anyway, so you could always spin the top before putting it back on if you want the logo to line up or something like that.
 
Yes it does make a difference. The inlet needs to be in the centre for an even spread across the cores with the outlet situated above, either right or left.

Well he said he had the inlet/outlet the right way round and I don't believe for one nanosecond that the orientation of the block makes any difference whatsoever, unless you're using the quad-core nozzle insert obviously.
