Haswell outrageous temps

post #1 of 9
Thread Starter 
So here's the deal.

I've been waiting to upgrade to Haswell, and it's finally here.

I was planning on buying a Corsair h100i for cooling. They are compatible with the new sockt, so np. However I've been reading a few reviews which suggest that even with the h100i, cooling on an overclocked 4770k is very bad... The temps are simply too high.

Can anyone confirm this, and explain how come this is so?

I was hoping to OC the 4770k to 5Ghz but apparently 4,7Ghz is as stable as it gets.

http://www.legitreviews.com/article/2203/14/

"It should be noted that we are able to hit 4.7-4.8GHz with the Corsair H100i water cooler and there is no throttling, so plan ahead if you want to overclock!"

http://www.bit-tech.net/hardware/2013/06/01/intel-core-i7-4770k-cpu-review/8

From here, though, the temperatures increased rapidly and we reached our limit of 4.7GHz using 1.257V and a scorching temperature of 98°C, and that's using a Corsair H100i, which we know to offer the best cooling short of a custom water-cooling kit.


I'm disappointed...

I'm disappointed too. Going back in time, Sandy Bridge processors and earlier used some sort of solder between the core and integrated heat spreader which gave good heat transfer. With Ivy Bridge, and now Haswell, they use a cheap thermal paste between the core and IHS. So even if you do have a good cooler temps aren't going to be the best. People do de-lid and replace the thermal paste which typically gives a pretty good decrease, but this obviously voids your warranty and can be a bit risky to attempt. So yes you can basically confirm temps are going to suck, and this is the reason why. I'm sure Intel got a lot of negative feedback on Ivy Bridge for the same reason, yet they would rather ignore their customers just to save maybe 5 or 10 dollars (if even that) on the production cost of each CPU.

Same as Ivy basically, you have to delid it to get the most out of it.
The name of the Delidded club here was already changed because we assume an influx of Haswell delidders. Give it a little time for some here to experiment with Haswell delidding, and see how it goes.

Edit: The problem with temps is not the TIM Intel uses, but the glue that hold the IHS on. They haven’t found a good way to keep the IHS on the PCB that allows good contact between the IHS and die.

Could it be that Intel don't want customers consumers to overclock.....?

look at Linus' overclocking Haswell video, he explains how the percentages work for different grades of CPU, only the top 10% should expect to reach 4.7. Its pot luck as to how well it will overclock. Research has shown that Haswell performs the same as Ivy bridge but at 0.2GHz less so a Haswell at 4.6 will perform equally well as an Ivy at 4.8

me myself i found haswell to run so hot 10%-25% hotter than IVY because they stuck the VRM's on the CPU die this added alot of heat and amplified the die to IHS contact issue and quickly degrades the OEM Intel TIM making it dry out and burn out which will cause temps to eventually become a constant issue i cant believe Intel hasnt learned from theyre mistakes they even went so far as to release a bunch of haswells that couldnt run stock clocks / settings on stock cooling without thermal throttling.


http://www.youtube.com/watch?v=KVaV7jaLXa0 perfect example of this on stock clocks / settings and stock cooling ( near end he explains about it thermal throttling ) another http://www.youtube.com/watch?v=gqr06oL_hwk so from here you can get an idea of what i am talking about it maybe rare but it happens due to an issue with the die to IHS contact and improper application of the TIM between the die / IHS by Intel at the assembly line and there has been a few that have been reported where Intels assembly process completely forgot to put TIM between the die / IHS . To sum the issue up Intel has been skimping for past 2 generations and not learning from theyre mistakes and continue to make same mistake to save a few $ on theyre end and give us the customers / consumers the ****ty end of stick.


I myself recieved 2 haswells that wouldnt even run stock clocks / settings under heavy load without thermal throttling on oem stock cooling with a coolermaster HAF 932 case with insane airflow also it took nearly a month and me paying shipping costs to get a replacement of each CPU over theyre f&%$ up.

im running 4670k @ 4.7 with 1.25 vcore. high 70's when running aida. 50-60 when gaming. im not seeing those kind of temps and im running a noctua d14. U should check the batches. The early ones seem to suck tongue.gif

That looks like an exciting and dangerous venture... I'm stupid enough to give it a try though biggrin.gif

However, my chip is running at 4.5 Ghz with 1.260V. Apparently that's an "OK" chip according to the thread? So I guess I could live with what I'm currently at.

(And my chip was one of the early ones. Bought it 2 days after launch).
