I was going to ask which Heatkiller, but there only seems to be one

so I've linked to the 1156 version instead.

Heatkiller CPU Waterblock Revision 3 LC (Socket LGA1366)
The Heatkiller CPU Rev3.0 LC-series offers outstanding value for money. The LC series was also designed specifically for the new generation of processors and offers great performance for little money
Heatkiller 2 in stock £26.99
(£22.97)

Heatkiller CPU Waterblock Revision 3 LT (Socket LGA1156)
The HEATKILLER® CPU Rev3.0 LT sets a new benchmark in cooling performance, build quality and user friendliness.
Heatkiller 3 in stock £34.99
(£29.78)


Who's in the know? Is the LT likely to be worth the premium over the LC?
 
The LT is the second best block currently available (behind the new swiftech XT)
The LC is almost as good and is less restrictive.
Both are MASSIVELY less restrictive that the XT

see skinnee labs - linky
I like skinnee's testing better than many of the others sites as he give results for low flow to extreme flow
The ranking can change - for example, the ek supreme is an excelent block BUT only when used with a powerfull pump.
Use it was a D5 on 2 and its poor.
 
Thanks for the link, it's pretty useful. I'll probably be running the pump (D5) at fairly low settings; at 2 it should provide ~0.7-1.15mH20, so I would've thought the LC/LT would be a better bet for me than the XT - given that there will be a chipset block and a 120.3 rad in the loop, does that sound like a reasonable assumption?

Cheers
 
I also ran my D5 at 2 (but the ek D5 xtop allow me to run at 3 with less noise!)
Worth a look...

The PA is about as low restriction as you can get - I have one for that reason
As for the chipset block - the ek's are low restriction as are some of the universal ones.

I use a XSPC edge as it's the second lowest restrictive block (fuzion v1 is lowerest)
to keep my flowrate as high as possable when using the D5 inaudibly.

In essance you have three options
You can either go with a enzotech sapphire (for highest flow possable and a bit more cash)
or HK3 LC for best balance
or HK3 LT for best performance (in low flow loop)

As it happens, the D5 I bought comes with the EK Xtop Rev.2 :D
How do they work, btw? Is the 'top' basically a different propulsion system for pumping the water?

An XSPC RX360 actually appeared on the MM, so I'm hoping for that one. According to Skinnee Labs, at 7.5LPM it'll have 25mmH20 resistance vs 29mmH20 resistance on the PA.120!

I take it lower flow rates at a certain setting (e.g. 2) mean the pump's having to work harder, and therefore increases noise, then?

Nice find - the Base (where the moter is) and impeller are the same as stock.
the 'top' is the area of the pump that sits over and round the impeller.
This has the inlet and outlet on it.
The ek top give 8-12% increased flow, reduced noise and G1/4 threads.
There is a review on skinneelab about them and the ek rev2 is the best.

The RX rads are better than PA at lowest flow and lowest rpm fan speeds.
For a quiet system they are the best, but there is very little in it.
Got my PA for such a good price, never intended using it - but works a treat passive.

The reduced noise of the D5 with a top is due to better hydrodynamics (less churning)
the noise any pump makes is engine noise and water/impeller noise and vibration.
The EK top reduces the water/impeller noise and insulate some of the engine noise.
The top does nothing to the virbration - but a soft mount will sort that.

Which is why a D5 with a top make the same volume of noise at 3 as the stock D5 at 2.

linky to my pump testing thread - post 43 has newest info

The RX is a go, just got to sort myself out a waterblock now :)
I shouldn't be stressing the pump or rad at all so hopefully I should be getting a quieter (and faster) system, good to hear about the noise drop with the EK top!

Cheers for the info.
