Was wanting to know if coolers for 775 are even close to good enough for cooling 1366 cpu's seeing on how the 1366 cpu's are like 25% larger in size compared to the 775 cpu's??
I was wanting something like the Xigmatek 1284EE as I think it looks way sexy with that clear'ish orange fan..
Really needing something more then the stock heatsink as it is just not cutting it with temps even at stock settings.
What a piece of crap..
Anyways looking at teh thermalright ultra 1366 version also- is the base of the heatsink the part that makes contact with the cpu larger then the 775 version or is it the same thing as the 775 version just with a 1366 mounting plate???

the IHS is covering the important thing you need to cool.

and most of the time, its about 33% less in size then the IHS your seeing.

SO how long before we start seeing real 1366 heatsinks not just the 775 with upgraded 1366 mounts..??
I just read several reviews saying how current 775 with the 1366 mounting are not cutting it due to the larger IHS in the 1366 cpu's and they are out putting more heat then 775 cpu's due to the larger IHS.

ummm take old sink.

use lga1366 mount

old sink becomes new sink with new lga1366 mount.


There wont be a specific sink just ment for the LGA1366's rectangular ihs. Because the current sinks right now have a large enough cooling head for LGA1366.

Do you guys honestly want an airsink weighting 2kg?? because this is what your asking for in a new sink... :p

I dont want the cooler larger just the base of the cooler that makes contact with the IHS larger..
Basicly your saying if I take an old athlon xp 2600 cpu cooler and buy a mount for an am2 it would cool a phenom x4 9950??
No it wouldnt just like socket 775 coolers wont cool near as good as a cooler made for 1366 socket...
Hence There needs to be an upgrade in the size of the Block of copper that covers the Cpu IHS.....FTW

The difference you are overlooking is heat load. The LGA1366 is a 130W TDP chip and many of the current LGA775 chips are 130W+ TDP as well.

Core i7 920 Specs: http://ark.intel.com/cpu.aspx?groupId=37147

Well I'm waiting on this TRUE-1366, not sure how it compares against a normal TRUE. Says it has more pipes and larger fin area, hope it fits in my new case.

Just to continue beating the already truly dead horse, but the Intel box cooler is a real POS.

Well this is my analogy plain and simple.
Lets say you have one of those old stoves with the coil burners one burner is small and one is larger.
They both heat up to the same temps right?
Ok now place a pot of water of the same size on both burners.
one on the small burner and one on the larger burner.
They both Out put the same amount of heat but one is larger just like the Core I7's vs the C2Q's.
The problem is the pot with the larger burner will boil first hence using the same cooler to cool a larger cpu that previously cool a smaller one will not cut it or am I wrong??

I understand your theory but in reality the base of LGA775 coolers are oversized to begin with. Once you de-lid the LGA775 and LGA1366 chips, the cores are not that different in size judging by what i've seen so far.

Q6600 with the IHS sanded off: http://67.90.82.13/forums/atta...825&stc=1&d=1227954849
Core i7 965XE with the IHS removed: http://www.ixtremtek.com/ixtek...5XE-3830A447/test1.jpg & http://www.ixtremtek.com/ixtek...5XE-3830A447/test2.jpg

Also, using your own example of the burners and same heat output, the one on the smaller burner would boil first because the heat is being concentrated into the base of the pan and thus into the water. The smaller pan on the larger burner would boil slower because the heat output not covered by the pan is radiating into air instead of the pan and water.

But, to correct your example, it would be more like comparing those same two burners only you would need to place a 14" square plate of metal between the burner and the pan (to simulate the IHS). This plate is going to absorb the energy from the burner and the pan would need to then absorb the heat from the plate. Now if you use a 12" pan and a 10" pan (such as comparing LGA775 and LGA1366) the heat difference would be minimal. But if you tried to compare a 12" pan and a 4" pan, obviously the 4" pan would not suffice.

no... your absolutely correct... which is why i tugged gillbot into water territory..

and from the sound of it, you need to be tugged into water territory as well...

Because if you keep thinking like this on air, you will seriously have a 3kg heat sink sitting ontop of your cpu...

Dunno if this helps the OP at all but I got my new cooler yesterday and here's what I'm getting compared to the stock fan, these temps are at stock clocks on the 920.

Intel Cooler:

Idle - 40C
Load(2 hours of Prime) - 72C

TRUE120 -1366

Idle - 30C
Load(2 hours of Prime) - 45C


Plus it's virtually silent, I'm very happy, will be doing some OC over the holidays.

ok ok ok so seeing how you guys think its ok i think i will give it a go with air again.
The other reason being is I just had to close of a call with this new water block I got.
I got a block with a acrylic top and what do ya know the damn thing cracked not due to over tightening or anything but due to water flow..
You Guys even told me to stay away from acrylic tops but I wouldnt listen but that wont happen again!!
Long story short No more water for me for a while good thing I leak tested before I set it all up.
Could have been $2 Grand right down the drain!!
So what of these 4 do you guys think I should go with??

1.Thermalright Ultra 120 W/1366 Bracket

2.Noctua SE 1366

3.Vigor Monsoon III 1366

4.COOLER MASTER V8 W/1366 Bracket

Actually, this isn't quite correct. The temperature of the two burners may be the same, but the larger one is holding more heat - that is, it has more energy to dump into the water.

Just so you know, the TDP Intel reports is short for Thermal Design Power. It's a measure of the amount of heat a cooler is expected to need to dissipate, expressed in Watts. Two chips with similar TDPs are expected to need similar coolers.

The size of the heat spreader isn't as important as you seem to think because it's not analogous to the size of the coil on an electric range. The heatspreader isn't a heat generator the way the coil is. The heat generator in this case (the CPU) is under the spreader and is what determines how much cooling power is needed.
