Ivy Bridge heat spreader fingered as source of heat problems.

[DanceswithUnix]

They changed how the heat spreader is coupled to the silicon.

Although if you read all the articles mentioned on that page it's the same suspect engineering samples they were stripping apart.

VR-Zone has a report here that supports the 'poor thermal grease' theory.

I am curious about this. A few good sites I read have recently been saying that ivy bridge high temps are due to the internal thermal paste intel now use.

I was wondering if anyone with an ivy has removed the IHS and cleaned the paste and noticed a big temp drop? Cause at least one site tried this and it didn't help them. Not sure who to believe...

Some many conflicting reports atm. Would be nice if Intel addressed it tbh

What is there to address? The thermal limit has been increased to 105C for the Ivy Bridge CPU's. Yes, they do run hot when overclocked but that's outside of Intel's testing and design scope. The most plausible theory I've read so far is linked to the nature of the new transistor manufacturing and the higher concentration of heat because of it.

I am pretty sure its not down to intels paste. new arch just heats like a mad hyppo and needs a mud bath own one myself, was using i5K prior to that, cant say there is a massive difference, only reason i bought it - price, £150, also originally i was aiming for pci3.0 even though that also doesnt provide much difference. However, if you searching for a perfect GPU like me, becouse i've changed around 10 different ones in the last 6 months if not less, then HD4000 which was upgraded in ivy from hd3000 on sandy, is handy takes less power, and well, does the job for me

I do believe that Intel's thermal paste is the cause of the very high temperatures. Ivy Bridge both uses less power (77 W as opposed to 95 W on Sandy Bridge) and is also more efficient, so less energy should be output as heat. Also: a guy over at another forum removed the IHS, replaced Intel's thermal paste with something else and re-seated the IHS. I think he lost quite a lot, 15°C at load or something like that!

Yeah it's almost certainly the cause; while the increased heat density due to smaller die size may lead to slightly higher temps given the same TIM, it doesn't explain the fairly huge difference seen with IVB. As I've explained on other threads, no thermal grease comes close to solder (metal) in terms of real-world conductivity.

15c load sounds mad, i want that..

I've read something similar. It's likely a combination of both the new technology and the thermal medium. Although the new IB architecture is more efficient, the concentration of heat is actually higher than SB when overclocked, ie. More heat per square millimetre. SB scales better with overclocking in terms of its thermals.

Fudzilla Link is making me pretty stunned. How can you use this fat knife!?
Why didn't he use a razer blade? So strange...he should have thought also about mounting. The video doesn't even give any clou about heat or what...

[Useless]

I have an Ivy i5 3570K and its cracking at stock speeds very cool its only when you start to overclock that the temperatures spiral out of control.

In terms of heat problems it is indeed a combination the of poor thermal compound (instead of solder) and the new technology (it just doesn't transfer heat away as effectively even with solder).

People that have replaced the Intel thermal compound seem to report much lower temperatures but still higher than Sandy at full load with same clocks.

Ivy is much better than Sandy at stock clocks however if you want to overclock then its Sandy all the way.

[Willzzz]

Plenty of people have managed to achieve decent overclocks with a 3570k.

They might not be hitting quite the same clockspeeds as Sandy Bridge, but 4.3ghz seems to be easily achievable and with the IPC improvements this is at least equal to a 4.5ghz sandy. Most games aren't going to benefit from speeds above this anyway if that is your primary usage.

Aria are selling plenty of 4.4ghz pre overclocked so I think the majority of chips can get at least close to that.

[HalloweenJack]

yes they have , they also say you need better cooling to achieve them than on SB.....
