    I have been taking some thermal measurements for my new Razer Blade 15 and am curious what other owners have been experiencing. Basically, I'm looking to see whether what I'm seeing with my Blade is normal or if it's running unusually hot.

    All temperatures are in Celsius. All tests were run with the laptop elevated so as to ensure a clear airflow.

    Idle CPU temp (average): 43.4
    Idle CPU temp (max): 61

    Prime95 & Furmark CPU test temp (average): 89.8
    Prime95 & Furmark CPU test temp (max): 94

    Gaming CPU temp (average): 86.8
    Gaming CPU temp (max): 100

    Prime95 & Furmark GPU test temp (average): 81.3
    Prime95 & Furmark GPU test temp (max): 86

    Gaming GPU temp (average): 80.6
    Gaming GPU temp (max): 87


    Idle CPU temp (average): 42.7
    Idle CPU temp (max): 61

    Prime95 & Furmark CPU test temp (average): 88.8
    Prime95 & Furmark CPU test temp (max): 93

    Gaming CPU temp (average): 82.7
    Gaming CPU temp (max): 100

    Prime95 & Furmark GPU test temp (average): 81.3
    Prime95 & Furmark GPU test temp (max): 86

    Gaming GPU temp (average): 76.6
    Gaming GPU temp (max): 80

    Undervolting seems to make almost no difference when running stress tests and when the CPU is idle. I am seeing about a 4 degree drop in temperatures when gaming.

    These numbers seem a bit hot to me. I've been considering opening up the laptop and repasting (if needed), but do not want to void my warranty yet (just in case).

    For those of you with hardware experience, are these numbers good, okay, or bad?

    It’s good with such similar temperatures I could sell my old Blade 14 1,5K in mint condition after over a year gaming usage. Btw did you mean undervolting or is it really underclocked somehow?

    If you haven’t undervolted it, as Joikansai says, those temps are quite normal. If you undervolt it, you will see a material (5-10+C) drop in cpu temps.

    Thanks for the feedback, I corrected the OP (I meant undervolt, not underclock). I'm a little surprised that I haven't seen significant temperature drops with undervolting.

    Did you set any multiplier limits or speed shift settings in either the front page, or FIVR or TPL pages of throttlestop?

    Sorry I didn’t see max cpu 100 on gaming, it’s bad, I misunderstood with average seemly. This CPU is little beast that runs hot, I’m afraid it will damage parts around even I saw support stated that’s okay. Did you experience performance drop in gaming like lags or huge FPS drops? Sorry can only ask since here in EU most Blade 15 is on the way from Hongkong I believe. When it comes I’ll feed it directly AC Origins to see how it can handle it, it’s better than prime95 to measure CPU;)

    How much were you able to undervolt it?

    I haven't set any multiplier limits or speed shift settings. I've heard that undervolting a gaming laptop's CPU sometimes just leads it to run faster because it can, resulting in similar power consumption and thermals. I'm going to look at my saved log files tonight to compare CPU clock speeds.

    I have the CPU undervolted by 142.6 mV and the Intel GPU by 65.6 mV.

    I figured 100 degrees was pretty toasty, I've got some spare TG Kryonaut on hand and have been considering opening up the Blade to see if it needs a repaste. Game performance was excellent during both tests, I didn't notice any FPS drops or other performance hiccups. I imaging AC Origins will be a bit funner than Prime95 :)

    Here’s my temperature doing “super” gaming mode with afterburner 190/600 (gaming mode is 100/300) almost double. It also depends silicon lottery, I got this. Undervolting cpu -150mv only don’t change anything on throttlestop. Fans Synapse max.

    How often are you seeing temps hit 100c?

    My apologies for a late response. During an hour of gaming, 26 seconds total were at temps of 100c (0.72% of the time). 139 seconds were above 95c (3.86% of the time), and 182 seconds were above 90c (5.06% of the time). I'm not familiar with whether these numbers are good or bad, it seems 26 seconds at 100c isn't as bad as I'd initially thought.

    Looking through the logs from Throttlestop has lead me to believe the heat savings from undervolting are allowing for a higher turbo boost, leading to faster speeds and similar heat levels. I'm thinking if I want to see heat savings I should cap the turbo multiplier (or disable turbo).

    Quick update - after applying new thermal paste and an undervolt, I'm now seeing average temperatures of 70 degrees while gaming (both CPU and GPU). Definitely an improvement! Only one spike to 100 degrees during one second of the 70 minute gaming session.

    Oh damn, I think thats what I'm in need of.

    For some one that doesn't have that great of an experience re-pasting and such. Is there any advice? Should I take it to the a computer repair shop or do it myself.

    Try contacting support hopefully repair center will do that for you. Provide them your temperature picture as a proof and tell them you prefer repair as replacement. It’ll take time but maybe it’ll be better than getting new one with factory thermal pasting imo.

    Sounds like this did the trick. Keep me in the loop about your temps... I am in daily contact with Razer about temps/power limit throttling and want to keep them updated.

    When I turned the PUBG, the average CPU temperature was 80 Celsius and the average GPU temperature was between 70~75 Celsius
    You are very high tempurture

    which fan mode are u using?
  17. misterg36

    So at the moment ALL intel chips run in the high 90s on pretty much every laptop and NUC/tiny PC I've tested.
    The worst hitting 107C!.
    With that in mind the temps look good before re-pasting and pretty normal with what I have experienced on non-blade laptops (Still waiting for the 4k in UK).

    The thing I found when testing, is that only using the GPU AND CPU hard will cause really bad temps, so when comparing, make sure you do that.

    eg. AC Origins and most UBIsoft games as well as Subnautica hit both really hard.
    Fortnight, PUBG, Destiny 2 etc mostly use GPU, so the heat is always lower.

    This also means that eGPUs can also lighten the load heat wise, as well as making sure fans etc are clean and clear

    I think I need to rma my blade. running prime95 and fur mark I'm pretty much pinned at 100c. this is with a -.160 undervolt and repasting. even when it drops down to 35watts I'm still hitting 95c-100c. This is in gaming mode with fans turned all the way up.

    I don't thing the vapor chamber is making good contact with my CPU. When I repasted, the thermal paste on the GPU was still wet while the CPU had spots of dryness. Also the repast improved my GPU temps by a decent bit, where as my CPU saw next to no difference.

    will a similar vapor chamber be coming to the blade stealth?
