Dilemma

post #1 of 12
Thread Starter 
Hello,

Currently got a 3770k for my new build wich has idle temp problems and imho high load temps undera H100i 90c max recorded on 1.255v

Idle temps on core #1 can be up to 20c out of range with the others and sometimes #2 has the same issue they run up to 52c on idle. After removing and reapplying paste using stock coolers with intel paste I had to give up and say that my coolers are never touching the CPU on the left side.

Had contact with my reseller wich wanted to check if it was the socket on the motherboard that was the issue or the ihs that isnt flush and asked me to take some pictures. They did offer me to RMA the chip to them so they can send me a new one but I wanted to see what you guys think about this matter before i actually return the cpu and be without it for a few days.

next pictures are from my 2500k wich i mounted to see if I could see if its the cpu or the socket on the motherboard but this is just weird in my eyes. Temp difference is 3-5 on the cores of the 2500k on idle and the paste seems to spread better on the old chip.

Would really want to know what you guys think about this.

PS: both chips are set on 3.7ghz and are 65c on load with my h100i

90c under a H100i.....that is definitely high.

What thermal paste are you using and what method are you using to apply it? 20c higher on 1 core usually means the paste is spread poorly. If it wasnt making contact I figured temps would skyrocket then BSOD.

My i7 only goes upto 66c under prime with 1.21v though. (Custom loop though).

Are you overclocking the 3770K at all? And if so have you done the delidding stuff? Because you havent redone the TIM then your temps would be in for a world of hurt.

I myself have always had temp variances of 5-8 degrees that have worried me but most people say that it is within acceptable range.

If you are not overclocking then i would be worried about the chip but if you are then ivy bridge has special needs that you have to do in order to overclock effectively.

As for the thermal paste spreading i really dont think it matters from chip to chip.. It all depends on how you lay the paste and how evenly you put down your cooler atleast from my experience.

I have had the chip on 4.6ghz then it reaches up to 90c with everything running at 100% even the cooling fans etc. On stock it runs in the 65+ range

I use Cooler Master as this is pretty much the only thing that is reachable within a day if i wanted something else I need to wait up to 7 working days to get it delivered (like ***) and i am using the pea in the middle of the chip.

65+ stock jeez. What are your temps with the H100i on the i5?

( I never ran ivy under air or anything less then custom loop lol, so not 100% on temps for it)

pretty much the same range 60-65 but idle temps are pretty much stable all round with a difference of 2-3 maximum on each core
post #7 of 12
those i5 temps are under load and at stock? Seem kinda high for a sandy.

If the i7 temps are the same as the sandy i would lean more towards the cooling....but still doesnt really explain why 1 core is 20c difference on the i7.

The picture explains it fully, it is either a series of bad mounts (super unlikely) or there is a bad seating of the IHS on the chip, or the socket is somehow misaligned on the motherboard. This does not look like inappropriate mounting, I would try to find out if the chip or the motherboard is responsible and RMA it.


If the chip is responsible you could delid it (relid it), but that would void your warranty. I would suggest returning it anyway if you don't think you plan to delid the chip in the future.

Would the Ivy chip boot on a Sandy motherboard?

If it will I can try and boot it up on my old system and see if the socket is bad or the chip

Sandy Bridge 6-Series (e.g. P67, Z68) motherboards will boot an Ivy Bridge CPU if its BIOS has been updated to its latest version.
