4770k here, 4.5ghz on 1.2700 v in bios, 1.264 idle in win 7 64. 1.280 at load in games. It can max at 77c in my pretty toasty room i n games under a k2 cooler with dual akasa piranha fans. Thinking it needs scalped.
 
It will shave 15-20c off your temps. If you can afford to replace the cpu if the delid fails then go for it.
What temps do you get running aida64 stability test, specifically cpu-fpu test only?
 
i get 94c inside 3 seconds of running p95 small fft. Chip is cooled by an alpenfohn k2 with dual akasa piranha fans in push/pull. But theres no warranty on my chip.
 
Dont bother man. Its not worth the risk for afew degrees C. Your system is stable at 4.5. Just use it and have fun.
 
If you put the lid back with better TIM then maybe only a few degrees. Leave the lid off however and expect at least 10C, and possibly 15-18C.
 
Use and decent TIM and get more than a few C and use Liquid Pro and you will get 10-20C.

I did on Ivy for a peep (used knife back then and told him if it dies its down to him).

There are threads here with peeps befog and after results and some are as much a 15-20C
 
Cheers guys, in gonna try a few corsair sp fans on the heatsink and replace the stock fan in a Lian Li 5.25 bay cooler i use. Airflow in this case isn't great which certainly doesn't help. Might have a go at lapping the chip and cooler sometime as ive had good results in the past. Far less risky too and as mentioned my cpu has no warranty anyway.
 
my conclusions from de-lidding

If it is purely for a temperature drop then fine but if its to gain more Hz then you need to know how your chip scales, under water this is quite easy as your not so temp limited.
The point at where you need big voltage increases to gain that extra multi is the place to stop and tune. No delidding or lapping is gonna make your chip use less voltage than it requires.
I am not temp limited in anyway and if my chip were a 4770 there would be no point in delidding as i would most probably kill the chip before any thermal limits were reached.

As your at 77c which is well below the 4770's Tj max i would not risk it and leave as is.

what volts does your chip require for 4.6GHz???

Get yourself some watercooling setter and never have to worry.

Most times when gaming its maxing at 67c, but the room its kept in gets pretty warm when the central heating is on. Coupled with very little air intake the temps start to rise. In changing cases soon so this should help, found that components run 5-6c hotter in the xl than my old loan Li A70F. Not really worried about clocking it higher as 4.5 is plenty for my needs.

Not tried 4.6 yet,but current voltages listed in op.

if your not bothered about higher clocks then i wouldn't worry, your temps are very acceptable and your at a good speed on the cpu.

If your after lower all round temps and a quieter PC experience look to water.

I can game passive(no fans) at 4.76 on the cpu and 1300 on my Ti with temps equivalent to air, total silence apart from a small hum from the pumps, its a very strange experience with no noise and lots of power!!

What case are you after rob??
 
Case wise either the Phanteks enthoo primo, (waiting to see the new special editions) or the new enthoo luxe. Tbf noise isnt too bad, gpu is extremely quiet due to the wf cooler. In games the total system is running at 40db measured at a foot from the case.
 
Another vote for water cooling. It's extremely unlikely to ruin your chip, it looks great, will reduce temps, and it's fun to put together.

Plus, delidding your CPU won't reduce GPU temps. :cool:
 
Gpu temps are pretty ok at 64c max, and very quiet. Watercooling would be nice but expensive. And the money would go nicely towards adding another gpu.
 
I enjoyed deliding mine and re applied the TIM then reattached it with black silicone, it has allowed me to get to 4.7 with temps of around 55-60c under full load, Without i was hitting 90-95c. my cpu isn't the best over clocker needing 1.37v to keep it stable so the delid was well worth it imo.

If/ when you come to do it you will see just how poorly the original TIM is.

To my disappointment I have found this to be true... thought I could push for 4.6Ghz or more on mine after delidding but no... temps are down, which is nice, but can't get anymore Hz out of the chip...

As for the risk aspect... of course there is some risk but I'm generally clumsy and very impatient yet I managed it fine (razor method).

i used a flexible hand knife (the ones you snap bits off as they go, and just pressed on the silicone from the corner. just don't let the blade go too far as you can hit the die quite easily
