Ivy Bridge heat problems remain even after IHS removal - eTeknix


We recently brought you the news that I.M.O.G from Overclockers.com had come to the conclusion Ivy Bridge was a hotter chip due to the fact there was an additional layer of inefficient thermal paste between the processors Integrated Heat Sink (IHS) and the processor itself which affected cooling efficiency. Naturally the only way to test this hypothesis is with some empirical testing and that’s exactly what a PC EVA forum member has done. Using a Core i7 3770K processor, with a Noctua NH-D14 CPU cooler and Prolimatech PK-1 thermal grease there was testing conducted with the IHS on and the IHS off to see if it gave any differences to thermal performance. The testing methodology involved using AIDA64 Extreme Edition for idle and load average temperature monitoring with Prime95 being used to generate the load temperatures. Testing was done at 4.5GHz with 1.2 volts on the core.
The results are summarised below in tabulated format:

As you can see even with the “cheap” thermal paste and additional outer IHS layer removed the cooling performance is still identical within a traditional margin of error of 5%, therefore its safe to say the high temperatures have nothing to do with IHS and are simply a consequence of the way Ivy Bridge’s revised manufacturing process works. In practice this now means Ivy Bridge will typically reach lower stable 24/7 clock speeds than Sandy Bridge but will offer similar performance (for example a 3570K at 4.8GHz is the same as a 2500K at 5GHz) and with slightly lower power consumption.

well,. may untag ma fix na jud ni nila na issue

[siopao1984]

kung mag release sila cguro new revision / design sa procie.

naa na ba comparison sa temps between 2500k/2600k og 3570k/3770k using stock speeds and stock Intel HSF? this is what i want to see...

[simoko]

the generated heat is due to the use of these so called 3D transistors or FinFETs & its channel leakage...Intel is still using ordinary wafers on the initial Ivy releases...they will be migrating to FD-SOI later...

bim27142: yes there are. I saw some while browsing around. I didn't bookmark the sites though. But none of them are big hardware sites. These well known review sites have SOPs to follow. Most of the time especially it is Intel, they won't give out the worst part of the products reviewed. Check Anandtech's and Tom's for example, they have all the information like benchmarks, overclocking, features, specs.. but no temperature comparison.

This is great news if u just bought a sandy bridge cpu or an Amd fan. At least di pa kaayo devaluated akong i5 2500k

[lloyd_joy]

any Sandy Bridge processor today is still updated... dili pa ni sila ma devalue kay ang Ivy Bridge is just an improvement on the Sandy Bridge... almost the same ra gani sila ug price... its just the temp on the IB's OC performance that is right now widely discussed in any where around the globe...

Thanks at least di pa ma ilisdan ang SB! overkill na man gani kaayo ang power sa SB! and the other competitor is very behind pud, so for me hinay hinay lang intel no need to rush. Nindot pag sawaan usa ug maayo ang SB! kay di pa raba ko dugay pud gikan ga upgrade hehehe....

Agay, murag fail ni da... Nag pang s*it na ang QA department sa Intel ron ba...
