News Haswell heat surprises system builders

Standard run of the mill retail chip first batch of official sale worthy stock in the UK

 

That's not a bad result at all - it's a big clock speed jump. Although 80deg is a touch too high for me - I like to max at 65deg.

 

+1 to showing us your settings and set-up

 

Can you provide a screengrab of smallfft running for an extended period with core temp and cpu z being displayed?

 

Why would I work for Scan or Ocuk they are like 250miles away from me both of them.

 

Maybe it's worth the commute. OCUK Owned by a German company now int they

 

I think we need to understand that the larger graphics chip is also responsible for heat. That said, for those who say this is underwhelming, remember that 65nm and 45nm were not exactly quantum leaps. Neither were the first 32nm chips.

In fact given that this is a tock. We'll see.

 

But don't they run cooler when not pushed to the max and not over-clocked? They certainly use less power and therefore should be generating less heat.

I thought the whole purpose of this chipset was to lower the power requirement rather than to boot overclocking potential?

 

I'm not sure but i think the "normal" temperature is about the same as SB, and i think much of this is to do with the way Haswell is designed what with the upgrade in the IGPU and moving the VRM's on to the chip.

It seems more components are incorporate with each new design, Memory controllers, integrated GPUs, northbridges, and southbridges have all moved from the MoBo to on chip

The reasons for moving components into the CPU are always sold to everyone as being a good thing, and i dont doubt that they are.
But you have to question what impact this has had on temperatures within the core, and how much faster current CPU's would have been without all that extra heat

 

When the heat transfer isn't great, sustained temperatures will be a bit higher. Also, Haswell suffers from the same problem as IVB: it doesn't consume a lot of power but it's a small die, meaning it will be hotter per unit energy consumed.

EK Water Blocks has released a cheap kit that allows users of existing Supremacy CPU blocks to remove the IHS and let the water block make direct contact with the CPU die.

If you think about it... it's kind of dumb having 2 layers of sandwich spread. First between IHS and CPU die... then between heatsink and IHS cover.

Why not get in bed with TIM manufacturers and actually put some decent thermal paste between the IHS and silicon. I don't understand why they would expose themselves to so much bad press for the sake of a few pence per unit. Even if they put the extra effor in with their K range so people can actually overlock the things.

I'm sticking with my IB i5 3330, nothing to see here...move along.

 

There is nothing wrong with the quality of the TIM used, the application of the TIM leaves a lot to be desired and could be improved.

It has nothing to do with cost and everything to do with moving components from the MoBo to inside the chip, along with the smaller contact area available.

 

Not again!

 

+1 !! Mine will NOT boot at 4.6 regardless of the vcore. It was even crashing in the bios when trying to dial it down. It's taking 1.35 to get it running at what seems to be a stable 4.5ghz. Getting temps of about 71 after a couple of hours of Crysis 3 with a Corsair h110. It's been a lot more hassle to OC than my 3770k was for sure!

 

wouldn't intel have more efficient chips if they just used solder. there chips would be up to 20c° cooler (you cant set it in %). but a lower temperature will increase the efficiency and it could get better turbo clocks.
this would enable longer low power sleep, lower power consumption at the same clock and maybe lower voltage all because of the lower temperature.

 

I'm a serial upgrader, every time Intel released a new chip set I have previously upgraded, this is the first time I will not due to the heat and negligible performance increase, i have cancelled my order and stick with my 3770k

 

There is no point in disclosing settings as these settings are unique to my CPU and my RAM and my Board.

Settings vary from CPU to CPU and they vary board to board so if I provided my settings they will most likely not work with your kit.

 

thats a cop out and you know it
