Delidding a haswell CPU - Worth it?

I'm using an old Alienware R1 as my living room gaming PC. Put an i7 4765T in there and it is more than powerful enough for what I'd need to play from the sofa.
The bad thing is, the temperature is pretty toasty (late 40s/early 50s idle), and it's not just down to the small enclosure. No amount of heatsink remount has fixed either. :(

Never paid attention to delidding before, but I'm starting to think there is a good few degrees to be found with remounting the IHS given the CPU age.
Has anyone done this recently on a similar aged chip?
I'd be doing this for temps and potential noise reduction only.
 
Yes, I've done this on a 4690K and a 4790K. The factory fitted thermal compound had turned to dust. I used thermal grizzly and temps dropped by 15C
Very worth it.
 
Yeah definitely worth it, haswell were notorious for being stingy with the paste. So many have done this with positive results though but also aware of a few that haven't separated well enough.
 
If you use a proper delid tool there is like zero risk for a haswell as they only use crappy paste and little bit of RTV to bond the ihs to the pcb. Comes off very easily.
 
My 4790k suddenly became uncoolable over the last couple of weeks. Yes the weather was ridiculous but could it be the thermal paste and not my H60 dying? I replaced the H60 with the stock cooler but now I'm thinking the worst. Asus real bench hits 99c in less than a minute and it's pretty cool in this room.

It's possible it's the paste. But Intel stock coolers are absolutely junk so probably no better than a dying H60.
 
if you look at the internal SMD components on the pcb, you'll see the best direction to nudge the heatspreader off the CPU. a bench vise or vice will do the trick and allow plenty of control. unlike 'tech yes (no) city' who used a hammer and chisel.

Aye, a minute is quite a long time and implies the issue isn't under the heatspreader. More likely be a matter of a few seconds if the internal TIM was compromised.

Still worth a delid if you're sure you're having issues but - that's a T series CPU so extra low power already. What temps are you getting that you need to get them down? The temperature won't affect boost or anything on Haswell so if it isn't throttling I'd not worry much.
 
The tool I got was 20¥ which is about £2.50.
Was incredibly easy to do, and the system was back up and running in 40 minutes.
The old paste was rock solid and turned to dust when wiped. :D

I used the end of a tube of quite terrible noname paste which seemed pretty watery... System in the early 40s at idle now, which given the heat of my living room is probably about right. Load temperatures were 4 degrees cooler in my non-scientific before/after.
I'll be interested to see how it performs with some good TIM. Was more concerned getting it back together today to make sure I didn't kill it.

There's still a place for old Haswell.

Nice job. My main rig is a 4790K and my mobile VR setup has a 4690K both under a NH-D14
