High 3770k temps after installing NHD14 + AS5

post #1 of 8
Thread Starter 
I just finished a new build today. Was previously using a Corsair H80 on a 3770k @ 4.5ghz/1.25v and using intel burn test, my highest temp was 77. I'm now using a Noctua NHD14 with Arctic Silver 5 thermal paste. Not using the same chip, but still a 3770k @ 4.5ghz/1.25v. Tried burn test again and temps spiked up towards 87 within two seconds so I stopped it. With no load I'm sitting at 30-33. I know AS5 has a cure time, but is this normal? Those temps seem scary. I used a thin vertical line on the chip as shown by the AS5 instructions. I'm wondering if I need to reapply/reseat. Also, the Noctua instructions didn't mention supporting lga 1155, but the 1156 bracket seemed to work fine - is this normal or could it be the mounting system causing space issues between the cpu and heatsink? Is there a special mount I need to get for lga 1155?

I'm not terribly familiar with AS5, but I'm certain that there is some error if temps are that high. The standard NH-D14 mounting system works with the LGA1155.

My bet is that you didn't take off the film on the bottom of the NH-D14. I did that when I installed my NH-C14 the first time. It's fairly easy to miss so it's entirely plausible.

Have you made sure that you're screwing the mounting until the screws no longer tighten? Usually, you have to go back and forth as you do the final turns.

Sigh, just reseated and applied the included NTH1, but two of my cores are still hitting 85-88 - the other two are 80-82. This time I just did a small pea sized application in the center of the cpu. Made sure all screws were tight on the fan mount too. I'm really puzzled by this.

edit: Could it just be I got a subpar chip? I know every chip isn't the same, but such a huge difference in temperature with a cooler that is better than what I was using seems pretty extreme. Tomorrow I think I'll swap this chip out for my old one is see if that's it.

How is the spread of the thermal paste beneath the heatsink?

It looked decent when I pulled it off the first time with the AS5. I can't imagine I'm applying it wrong or anything. If anything, the first application was too much since I used the vertical line method. This time I used the small dot which is recommended everywhere.

I would say that yes you got a generally not great chip.

Because Ivy Bridge is thermal pasted/glued you get stuck with chips that are totally different on a whole new level as some have a better thermal paste application then the other and vice versa. You can see this with the two cores being hotter then the rest. Fortunately you can de-lid it if you wish! thumb.gif

Like others are saying, id guess its down to the chip at its thermal limit. Whilst 1.25v aint that bad, it usually doesnt heat up til around 1.300v. I would try a reseat first, then consider delid if you want lower temps.

For info these are delid temps you could expect with a good setup (1.27v)

Delid your cpu would redice 30c with CLU on die
