?

Does your AW13R3/15R3/17R4 suffer from CPU core temperature differential?

  1. Yes, over 20C difference

  2. Yes, over 10C difference

  3. Tolerable, within 5C difference

  4. No, within 1C difference

  5. Yes, over 10C difference, received after March 2017

  6. Tolerable within 5C difference, received after March 2017

    There is actually 3 different 13 r3 heatsink revisions. I've talked about this before.

    @propeldragon, thanks for replying that, can you point me towards the information i need on the heatsinks. for the 13 R3, and do you know of any part numbers and which one is best?

    Also for all others to have I found this nice guide on reddit, with size and location of the different size thermal pads, https://i.imgur.com/KDY0Emb.jpg
    and the following post, link after the text.

    Basically X-red = 1mm pad and O-blue = 0.5mm pad and White pads on the right lower side of photo is 0.1mm these can be bought from https://www.aab.com.pl/ . but not with a revolutionary conductivity, you could possibly just use a firm viscosity paste here. or re-use the old ones, i might try kryonaut here.

    I am going to try repasting again with kryonaut instead of Noctua NT-H1, and 0.1mm pads, ill post results. before and after.

    They all have the same part number......sourced from 2 manufacturers and multiple versions depending on which GPU you get. But not like an actual improvement of design like the AW15R3/AW17R4.

    Careful, with Dell stock pads, on my machine the 0-blue 0.5 were making absolutely no contact with heat-sink. So instead, I used Gelid pads 1 mm there too, and made them about 0.7 mm by compression with glass plate pressure.

    Dell is using the pad thickness as in the 'O' and 'X' picture, but it could be very 13 R3 laptop specific if they actually make contact at all with heat-sink.

    Good luck with your re-paste !!!

    OK I was curious if there was a point in possibly changing to the better one of them. I have a i7 7700HQ.

    Thanks mate

    Good stuff to know, I think I'm pretty well stocked now, and possibly bought to much thermal pads and compound.

    This time around I'll try dry testing everything a couple times to be sure everything has contact.

    If you got the 1060GTX and the 7700HQ config you already got the biggest heatsink for your system. They ship the crappy ones with the 1050, core i5 systems. Parts of the heatsink are shaped and soldered by hand so there is quite some variety between heatsinks still.

    Well 5.1cfm to 7.4cfm is a big improvement to me.

    Heatsink can be not labeled, s-j-1, and s-j-2.

    @c69k @rinneh @Vasudev @propeldragon

    First of all thanks for being helpfull guys, it seems a thourough repaste did the job and made my system stable again, and you guys comments helped me the right direction.

    As paste I used Thermal Grizzly Kryonaut, on CPU and GPU, I used the X method as described by Thermal Grizzly.

    I Used a combination of 1mm Phobya Thermal pads (carefull these are more rigid) And 0.5mm Gelid (these are soft indeed) and 0.1mm Pads from AAB in poland not very high Conductivity but they did the job.

    As described earlier, the Heatsinks are semi handmade and not 2 are like so I took quite sometime to make the thermal pads fit, by doing dryruns, and using an old cheap paste to guide me so i got an even spread on the CPU and GPU, checking for a fit of all the pads and spread of paste, and NOT following Alienwares standard pattern, of where to place 1mm and 0.5mm, actually at one point i had to stack 2 Gelid 0.5mm because the Phobya 1mm was a bit rigid and didn't quite fit.

    Anyways system is stable and below are results on CPU GPU and PCH, notice that when you undervolt the system and overall temps drop, the temperature on my PCH drops too. after 2 and 1/2 hours of playing Sea of Thieves.

    But im still planning on doing a PGS heatpipe to the Heatsink for more stable temperature on the PCH, as it keeps climbing towards 90+ during gaming.

    No undervolt

    With undervolt 0.130 and using MSI afterburner on GPU

    what is the best heat sink part number or version for the 15r3 with 1070, is the 1080 heat sink different?
    i currently have AT1JM005ZC0 85w-nv-e1-g2

    Ive gone through 3 mainboard replacements plus repad and different paste and can never get the temps to be decent or within a close range with each other.

    please let me know if there is a better version that I should search for. I just want to stop overheating while i wait for the new ryzen laptops to come.

    Thanks in advance!!
