ahh another one of these
ok time for another basic explanation on how cooling works...
haswell 4670K has a TDP of 84 watts. meaning it's designed to draw 84 watts. it draws more when OC'ed, but even OC'ed it rarely ever reach or exceed max draw of the chip unless it's under synthetic load. so as a general rule of thumb 84 watts is a "fair" number to use if you are talking about gaming loads.
the reason haswell is "hotter" (just like ivybridge) is because it's using the 22nm fab process. meaning it has MUCH higher thermal DENSITY then in the past. so... it's using less power but producing heat in a much smaller area. (kinda like the difference between a light bulb and a laser) the result is less energy to cool down, but VERY concentrated in a small area so it's actually harder to cool down (due to the much reduced surface area available for heat transfer.)
intel themselves have said that ivybridge (and hence applies to haswell also) will show a higher temp because of the increased thermal density of the 22nm manufacturing process. the PROBLEM is NOT the ability to cool down 84 watts of heat (sandybridge 2500k has a TDP of 95 watts so technically speaking putting out MORE heat then ANY ivybridge/haswell chip) but the ability to TRANSFER that heat from the chip TO the cooler to be cooled down is reduced due to the increased thermal density.
so... the problem for the current gen 22nm chips is TIM, not the cooler. even the lowly hyper212 did a great job cooling down the 2500k so you are saying a chip that uses LESS power requires MORE cooling?
NO... the key to cooling down ivybridge/haswell is higher quality TIM so you can TRANSFER that heat to the cooler in order to reduce the temp of the chip.
well... hope you understand the concepts behind what i just explained.Edited by psyclum - 7/11/13 at 9:07pm
