Delidding 4770k?

[Hank_Tech]

I'm getting a new motherboard for my rig and I was thinking that while I have my 4770k out, I may delid. Right now it's under an H100i cooler, all fans running at 500rpm for silent gaming. If I run Intel burn test, temps get up to around 80c. I could easily bring those down if I turned my fans up. But, if I have my CPU out and I want to try my hand at some better overclocks, should I delid? I would throw Noctua NT-H1 under the IHS. Is it even worth it? if I do it, should I go vice or razor method. It seems like vice is easier, but I'm not sure. What does everyone else think?

if you delid BE CAREFUL!!!! i cannot stress this enough, i broke my i7 by not being careful (i broke a capacitor off the bottom, RIP)

 

it will be worth it, haswell were know for bad paste on their chips.

 

also id do it the vice way, holding a thin razor is hard and i cut my hands up pretty bad trying to do it.

Yeah thats the main reason I want to use the vice. And i know Haswell is known for garbage TIM. I just can't decide if the risk is worth it.

If you have a proper vice (permanently mounted to a table) and it has clean edges to hold onto the CPU without chipping or gouging into it I would say it would be eazier. That said the razor method is not hard and if your very very patient should only be a minimal risk. I have done both methods first time I did it was with a (clamp on)vice and the wiggle that the clamp added it took a lot more force to get the lid off than a regular vice.

[FatPenguin]

Sounds sorta risky. maybe buy an old pentium to practice?

[arronleeds]

it all depends on how old the chip is, my lid was hard to get off due to the cpu being hammered and the paste stuff being solid, my new 4690k could have easily been delidded but i didnt wanna break another.

If your CPU's temp lowers with increase of fan speed, the thermal interface isn't the problem. When setting fanspeed works with diminishing returns, then your thermal interface is the problem. 

 

I wouldn't recommend delidding, not unless you don't plan on selling the chip later down the line and you're doing it for the hell of it (and have the disposable income to buy a new one if you brick it).

I just took the time and delid my 4790k. I didn't wanna use a razor black or a block of wood and a hammer, so I used the vice only method. I just let the CPU do all the work for me and dropped about 10c, but if I had some collabatory ultra it'd go down more. After the ihs was removed I cleaned off the thermal paste, took a credit card ( old drivers license ) took off the black silicon, applied new thermal paste and spread a thin layer out with a card, and I put the ihs back on and held it in place while putting down the mobo socket tensioner. Done!

Just not too old if its too old you might be practiceing on a soldered or epoxied chip

Yeah I have a permanent vice mounted to my workbench. I would probably use thick electrical tape or a bike tube to make it a little bit softer. It is on a workbench so it has been used for some "dirtier" things, I would make a little clean setup to do it though

yeah I was thinking one from like 2005 or somethin not like a pentium 4 or 3

Chip is a year old at this point. I don't know how hard the TIM is now.

What is the vice only method? I have seen the woodblock and hammer+vice, but not the vice only.

I'm not gonna sell the chip. A 4770k will be good for me for a looong time.

Unless you brick it in the process :')

 

Also, know that delidding only really reaps benefits when using something like Liquid Ultra. But using this stuff means you also have to isolate the SMD's of the FIVR near the chip with some epoxy or latex to prevent accidental shorting. Since that TIM is conductive as hell.

 

If you're planning on delidding and slapping MX4 in there, don't f*cking bother

I actually placed tape on the vice, and then I used some note cards on the CPU/vice grip side. So basically get the CPU in place and hold it with one hand while you tighten the vice with the other... You'll have to give it some force to turn it, but you'll feel some of the tension release,which means you did it right... Honestly, if you're gonna do it use thermal grizzly! I currently have Noctua under it, and it's not bad, but thermal grizzly is better. It can be bought at performance pcs

Would be using NT-H1 from noctua. Thats the main thing im wondering because I dont want to mess around with liquid metal type stuff. Is it even worth it to delid if that's all Ive got? Ive seen people get about 10c drops.

[Majestic]

I dont want to mess around with liquid metal type stuff.

 

Then don't do it.

[arronleeds]

if the chip is one year old and has also being ocd it may be tricky, mine was a stock 4790 so had no oc and it was solid as hell.

Ahhhh. Think I'm just gonna pass then. I am getting a Z97 motherboard so if I need a higher clock I can always try and sell my 4770k and get a 4790k used or something. 

 

Then don't do it.

Alright then. That's what I was mainly worried about. Saved me a lot of hassle.

It takes a while if you wanna do it right! At this point I really don't recommend it...

4770k is still a monster cpu mate, its the 2nd best 4th gen i7, people  say the 4790 is but if you oc the 4770k it shits on it.

Just to give you an example what the actual difference is. MX-4 has a thermal conductivity of 8.5 w/mk. Liquid Ultra is 38.4 w/mk.

It's not even funny how Liquid Ultra utterly stomps on all TIM's when you're applying it between the chip and the heatspreader.

 

Check my sig, that's a 4670K @ 1.368V running on an H105 after applying Liquid Ultra (prime95 27.9)

With MX4 i was still getting 70-ish degrees.

Damn, hovering right around 55ish degrees with an H105 on those voltages... impressive.

It all depends on how your i7 overclocks.

 

As an example, my 4790K was running@4.6GHz/1.22v, but was hiiting the temp limit.

 

I de-lidded it and now it's happilly running@4.8GHz/1.33v/80°C max (prime), and bench XTU@5GHz, and all 3DMark's@5.1GHz.

 

On another hand, if you are already hitting high vCore@4.5GHz (1.25v or more), it's not worth it, as it means your CPU is not a good clocker, and, except for loosing warranty, de-lidding won't bring you much.

[EvilWiffles]

Vice method 100% the best method.

Put down some nail polish on the SMD caps just to be sure no CLU will slide to the caps as you put the IHS down.

 

Skylake also uses the  crappy TIM and it'll be like this for all mainstream processors. So you'll benefit greatly delidding the Skylake line.
