    I'm in the process of saturating my water loop to record the temperature of this hot bugger of a cpu.

    Ok I've got the just of the de-lidding part and cleaning the tim off and also the gasket. I glue the gasket because I'm a stickler for perfection plus why not?

    Why glue back IHS, not neccesary...

    for CPU bare Die you will need liquid metal, dont use any other solution there, will screw your temps even better, so lets iron the things here,
    1. you must delidd, recommended method: Razor blade, be wise, dont use vice hammer method, its way to dangerous...
    2. clean all glue leftovers... also TIM present there... if possible use isopropyl alcohol,
    3. when everything its clean, like a mirror, you might: apply liquid metal to bare die... sit processor without his I.H.S., when processor its on its correct place you finally put lid over die, leaving it as you got it when purchased, be careful when placing lid back, close the socket clamp and call it done!

    Unless you are super anal in the cleaning, it is highly likely that you will see a ghost of the old epoxy left on the green PCB to help with aligning the IHS. Depends on where you read, but many say to just put the CPU in the socket, add TIM to the die, and set the IHS on it and lock the socket clamp on it. Have not done this myself, just passing on what I have read prior to this.

    I used the razor blade method and took only a few min to pop it off.

    Ok I cleaned it up as best as I could without scratching the pcb. I took a fine Sharpie marker and traced the outline, I used the ArctiClean 2 part cleaner.

    I noticed that with the lid off the pcb was convexing upwards, so anyways after all was clean I used Gelid Extreme paste and did a real thin even spread over the die.

    Dropped in into the socket, took the IHS and used my marking as a guide and then tried to clamp it in place but the dam thing would slide downwards from the sockets clamp.

    A few adjustments and I got it bang on. I then put the water block on and tightened it all the way down as normal.

    Now the lid's glue can cure as is, and I am anal about perfection but lacking a proper clamp to let the silicone dry I did what I thought was best.

    And it posted.. I saturated the loop for 2 15 min Realbench stress runs for a base line and after the remount I did the same.

    Only difference is a +5c ambient room temp with the dam sun poking through the window but all in all I'm happy.

    before de-lid

    66-67-64-65c

    After de-lid

    59-61-56-58

    So a difference of -7c -6c -8c -7c

    Could it have been better? I'm sure it could've if I used liquid metal but I used what I had laying around. Plus a few heat cycles I'm sure the temp's will be lower yet.

    weird that your minimums are lower before delidding.. or is it? or is that just warm up showing in the temps?

    It was at start up the min was lower and the room was cooler is why..

    That's one thing I couldn't control was the ambient temperature as I was focused in the job at hand and wasn't thinking it was warming up in here.

    Tomorrow after the gasket is cured I'll be pulling the block to check the spread on the tim.

    I have to agree here! Not worth all the effort for just 7 degrees at max. Might be why so many are using liquid metal paste though over the usual TIM offerings.

    I think for a lot of people it's not so much in the numbers as much as it is "the thing to do". Personally I've never done it nor would I , not even if it cut 20° off my max. But I suppose this is the nature of the enthusiast beast :)

    I don't understand why you were in such a hurry to delid if you didn't have the adequate Thermal paste = Coollaboratory Liquid or Grizzly

    noticed a big drop on my 3770... never goes up to 59C even on stress tests...

    I think he said ambient were different.. so, keep that in mind (1:1 C)

    Yes that's true but it was an experiment, I can honestly say I did it, I can re-do it and if one never tries they sit on the fence wondering and just watch life pass them on by..

    And @Knoxx29 it's easy sitting behind a keyboard and :shadedshu: at me, You go on about how cool your system runs but you say...

    I'm not using my water chiller, how do we all know that??

    Did you de-lid yours?

    And who said I was in a hurry?

    See I'm running the same as Knox and same clocks, voltage and yet my mobo is reporting 50-51c but yet real temp is showing 61c so what gives?

    I can honestly say by touching the loop and block and feeling the air coming off the rad it is indeed a lot lower then yesterday so I'm stumped..

    @Knoxx29 before de-lidding you'd had the temps i am having on mine right now, at the same frequency. Obviously different chip, but seeing them made me wonder; considering i'm using a stupid Corsair AIO (all in my specs) and i got double the cores at said same frequency, does it mean i should be happy getting low thirties when at low load?
    Was like low twenties despite the OC, but after sorting the RAM out, +0.35 vccsa + 1.44 DRAM voltage, we erm, kinda went upwards pretty fast. Right now for example am at 29, core always, not package. Later in the day i'm pretty sure i'll be up to my usual 30-34.

    (say something positive, yes. But also don't lie. lol)

    Am worried about the summer.. right now is.. right now. Gotta plan for a full 10C upwards come the time. Edit: long live AC units. My 9370 and the AC were like best mates, lotta love, lol

    But then again he's on a Z170 where I'm on a new Z270 and only 2 bios's are out and I'm sure a sensor is fucked up or ASUS have cranked the volteges up on me..

    I'm not familiar with this board yet and what voltages can be turned down, so i'll give him a tiny benefit of the doubt but not that much.

    I need to go check other sites out where big balls don't matter, where ppl will actually help with voltages, Like Dog said to a fellow clocker to go check his site out as theres heaps of info there un like here.

    I think we had a communication breakdown here :)
    (it's always the same)

    You probably mistook my question to Knoxx as a statement or a (in)direct comparison between either one of us, none of which is the case. My fault regardless, as i shouldn't have intervened at all; end of the day, am on a different chip. So my bad either way.
    As to helping, am thinking it's more of a gultural gap/misunderstanding than any actual unwillingness. They are both (knoxx and earthdog) pretty quick to respond when asked and not just in this thread, i mean generally.

    But either way, research is research, yeah. You could have done more reading first/elsewhere, but that applies to everything. As to voltages, well, one assumes you'll find more on OCing in an OC-focused site than in a general tech site, goes without saying :)

    I think a metal based thermal compound will bring things up to snuff. Gelid is good for IHS to cooler, but for a bare die, the metal stuff (like the Grizzly stuff and Coolabratory stuff) it makes a pretty big difference.

    I run custom and all in one loops and I have to say some of the best numbers I've got personally were from corsair all in ones. My H110i GTX is a beast, What all in one are you running from corsair ? Never mind I'm on mobile so I couldn't see your system specs until I turn my phone sideways .

    Realtemp never reports actual temps, no software will report actual voltage or temps its a given fact. You want actual temps buy a temperature prob, even then they will not be precise.

    @Knoxx29 i thought the pics you posted earlier were yours, lol.. showing an i7 7700k "before delidd" running at 4.5MHz at 30+ - 35 c? That wasn't your chip, lol?
    My apologies if so. Though question still stands.
