Well, where do you think the heat in that water ends up? It goes into a radiator, a "heatsink", where it's cooled by fan that pushes this "air" you seem to be so against.

Think of a tower CPU heatsink as a shrunken water cooling loop, except that the water tubes are replaced by heatpipes. Water-metal heat transfer is worse than heat transfer with a heatpipe.

Also, yes a water cooling loop is usually better for cooling. That's not the point being argued. I was disagreeing that heat transfer from a CPU to a metal block would necessarily be better just because there's water above that metal block.

The voltage he used was 1.27v which is enough for 4.7GHz in many cases. I would expect a 10C+ drop with a soldered chip considering he gets 5C load drop with just good thermal paste.

no way solder will get you 10c better, no way in heck.


22nm ivy bridge with trigate is high leakage , thats it.

Sorry people no way around it, have you people even seen the temperature graphs?


Ivy bridge temp is even cooler in some cases stock vs stock against sandy bridge.

As soon as you raise the voltage, temps go insane.

THAT IS NOT THE IHS OR TIM

That is called High Leakage

Electricity starts to move in areas it should not move into, causing insane temps.

Usually it takes alot more voltage for Leakage to start

But on ivy bridge it happens much sooner.

I believe the reason The guy that tested the exposed chip with the D14 didn't get improved temps was that the small internal block simply couldn't dispose of the generated heat quickly enough if it's in contact with a metal surface with no liquid involved as the heat can't escape efficiently,
I really hope I made at least a little sense. I'm so tired that I had to work on what I wrote for about 15 minutes just to make it partially understandable.
I`m up at yonge and finch area , kudos to you for being brave ! I`m building a TEC cooled 3770k system with 3 loops and will be mounting my EK supreme directly on chip with the Cool liquid pro. Have to put in order to Froz cpu end of next week, waiting on Mindchill`s dual tec and controller to be delivered. Can`t wait to see what stable temps it will achieve. thanx again for being a sacrificial lamb ! thumb.gifcheers.gif

Assuming all else is equal, the air cooler is better because there are less middlemen for transfer inefficiencies. However, things are often not equal because the last portion, the "Metal > Air" part, is usually better in water cooling due to superior radiator placement, total surface area, and number of fans.
Edit: I suppose an air cooler would have an equivalent "liquid" transfer point within the materials of a heatpipe, but the thermal conductivity there should be vastly superior to the water-metal interfaces of a water cooling loop.
Sorry but a well done water cooling system will murder the best air cooling solution, however air is a lot cheaper and does not inherit any of the complex problems and solutions needed to achieve relative stable temps. Both have pros and cons no absolute answer. thumb.gif

So, the solution to High Leakage increased temps is Intel's use of an inferior thermal transfer material than it used on a previous cooler chip?doh.gif

+1 to the OP for doing this! :thumb.gif: and..you have to take off the socket retention plate in order to get proper contact with the die...The top of the die die sits lower than the retention ..err contraption..have your case on it's side..be very careful..
Take care to not tighten it down too much.make sure it's flat on the die...just snug is good wink.gif
Glad he used MX-4! :yessir.gif:
That coolmastuff looks like it could bad if applied directly to a die.

Did you just skip the OP? He saw -5C just from MX-4 paste.

And follow the link at the beginning of the post---that person saw -20C with Liquid Metal Pro.
