Gabe any tip on who will get it sooner on europe ?![]()
Ok thx![]()
There are several vendors already with Ci7 waterblocks, but unless error or omission on my part, I don't see any of them with an adequate motherboard back-plate.
Swiftech recommends the use of an extended back-plate where high clamping pressure is applied (typically to improve TIM joint). By "extended", we mean a supplemental back-plate to reinforce the stock solution. Here is why.
The distance between mounting points in socket 1366 is quite a bit larger than that of socket 775. As a result, the motherboard is subjected to much higher flexing forces because of the leverage effect. This is the reason why Intel specified a back-plate with this socket. In Desktop applications, this back-plate is barely larger than the socket though.
One may wonder why the stock back-plate does not extend all the way to the mounting holes, and the reason is simple: in mass market applications such as Desktop, I suspect that OEMS are expected to use the Intel stock cooling solution which snaps into the motherboard without removing the later from the case. In this scenario, the mass (affecting dynamic forces -occuring in shipping for example) and clamping pressure (static forces) of the stock cooler are adequate with respect to motherboard flex and the existing relatively small back-plate.
However, in server applications where heavier cooling solutions are needed (imagine a large passive heatsink for a 1U application for example) it would be logical to speculate that one-piece back-plates fully extending to the mounting holes and featuring sturdier fastening mechanisms will be the norm.
I make this point to illustrate the fact that an extended back-plate is highly recommended to prevent excessive flex of the motherboard in heavy duty cooling applications. Not because of the mass of the water-blocks obviously, since they are all much smaller than massive copper sinks, but because of the high-clamping pressure (static forces) that we -overclockers typically apply to improve our TIM joints.
If you add to this the fact that some vendors release crude (dangerous) retention mechanisms which allow end-users to crank the pressure much beyond what the PCB traces can safely sustain, one can be seriously concerned about damage to the motherboard.
We at Swiftech spent a great deal of time (and $) developping a retention mechanism that is both effective AND safe.
So when you guys are looking for cooling solutions out there, all I can say is: buyers beware!

CEO Swiftech
I would first like to thank Gabe for not only such an excellent
product but, for also interfacing with the user community
'which seems to be a rare thing'.
As can be seen in the pics below, i am using a koolance bracket
i hacked up to be able to use my existing Corsair Nautilus 500
water block. I just could not deal with the HSF temps. I am in a
none AC home office and thank god it is not summer time where
temps can easily get to 80F in here. Even with this setup i am
getting idle temps of 45C-48C on the CPU and 45C-47C on the
chipset. Load temps can easily get to 80C-90C on the CPU and
48C-51C on the chipset when clocked at 4Ghz. Because of this
i am currently running at 3.6Ghz with idle temps of 41C on the
CPU and 45C on the chipset. These temps at 3.6Ghz is just not
acceptable to me.
As i plan to purchase a Swiftech GTZ in a couple of weeks 'pay day',
my question is. What is the model number to order a GTZ that comes
with the 1366 bracket rather than purchasing a GTZ-775 + 1366 bracket.
MY second question is what model number water block do i order for
the chipset on my Asus P6T Deluxe.
***TIA***
