i7 4790k - Post Delidding Issue ???

post #1 of 14
Thread Starter 
So a few days ago I delidded my i7 4790k using the vice only method, came off easily.

I cleaned the crap off the bare die and the heat spreader. Took off as much glue as possible too.

Reapplied NT-H1 thermal compound to the die, and on top of the heat spreader to re-mount my Noctua NH-D15 Cooler.

Only problem is, my temps seem to be slightly worse than before. I am running my CPU at 4.8Ghz @1.320V, and I just test it in games and check HWmonitor on temps.

I was getting around 70C 67C 62C 59C, and now I'm getting 71C 70C 65C 60C.

I have tried re-applying and reseating everything, and I have not yet seen these 10 to 20C drops in temps ??

I just ordered Liquid Pro Ultra based on a comment I read saying, "If you are going to delid, ONLY use Liquid Pro."









Will Liquid Pro between the bare die of the CPU and heat spreader solve my problem???

Generally liquid metal goes between the IHS and die. It is more common to use standard TIM between the IHS and heatsink after.

That's what I meant. So I would use liquid pro on the delidded die. Then put the Intel Heat spreader back on that, then just mount my cooler normally and use normal paste for the IHS and CPU cooler ???

Looking at your pictures I think that you need to remove the rest of the glue (black stuff) so that the lid will set as flat and as close to the die as possible.

Also, I used Coollaboratory's Liquid Pro between the die and the lid plus between the lid and my HSF. I know a lot of people that did it this way rather than using a different paste between the lid and the HSF.

Based on a similar thread that IDC started on the AT forums, I'd agree: in fact, the first thing that struck me was that excess glue. I think that normal TIM will spare your heatsink, though.

Thanks for your help dude. Ill get rid of all the glue somehow. Tomorrow my liquid pro should be coming in. So cant wait to test new results.

Its wierd, although I am noticing worse temps (not liquid pro), it seems that after the delid, my CPU sensors are acting strangely. In HWMonitor, my CPU temps in the desktop will hit 82C!!! but the moment I look on the current temps, its at about 35C, how does it just jump that high???

I opened RealTemp too, and my first core hit 68C immediately followed by 45 41 39.

Its hard to know my true temps, if all I look at is the maximums when all they really do, is spike up to it randomly even though they appear to hover in the 55C range, under gaming load.

Why ?

It might be the versions of HWMonitor and Realtemp that you are using.

When you first turn on a PC and just let it set at idle it is not uncommon to get a max temp 10C to even 20C higher on each core than what it is idling at (say 30C as an example for each core at idle then a max of 50C or so is not uncommon at idle). Each core will not idle at the same temp, you can see easily see a 5C to 10C difference at idle.

The lower your core temp the less accurate the temp monitoring software will be. The more load on your CPU and the higher your core temps the more accurate the monitoring software is.

After you boot your PC let it idle for 5 minutes and then reset your monitoring software, then see if your max temps seem more reasonable.

Is the 82C on one core, all cores and/or the CPU package? If it is only on one core then the temp sensor for that core could be the problem. If it is only the CPU package then maybe that sensor is having a problem.

I know this is the case on AMD CPUs, but had never heard that about Intel. Do you have a source?
