    Diablo 3 is the first computer game I have ever played.:D

    My last MacBook was not capable of operating such a game so I only used it for surfing the web, typing documents, keynotes, etc...

    Anyway, I love Diablo 3 and have become highly addicted. In fact, I've also downloaded Starcraft 2 and World of WarCraft.

    I have noticed that playing these games on my rMBP has causes the fan to run on high and the computer gets really warm.

    I know this is normal, but I just wanted to know if running the fans on high because of the increased heat would eventually mess up my rMBP.

    I'm not a gamer and Diablo 3 is really the first game I have played since the GameCube. So this may sound like a really stupid question, but I just want to make sure i'm not messing my laptop up.

    Also, if this is an issue what can I do to cool my laptop down? I've seen several laptop cooling pads at Wal-Mart and BestBuy. Would these be effective?

    The highest my temperature has ever been was about 105 degrees and the fans once reached over 3050 rpms.

    One more question, If I turn "Automatic Graphics Switching" to off while playing these games, will that help the performance of the game or help my laptop to keep itself cooler?

    DIII has been known to cause rMBPs to explode! :rolleyes:

    Well, assuming you mean Celsius, 105ºC is pretty warm as far as my 2011 'not rMBP' Macbook Pro goes .. but 3050 RPM is surely not that fast.. MAX is up near 6000 RPM I would think.. :apple:

    You'll be fine. It won't damage itself from overheating. There are thermal sensors in the hardware to make sure that doesn't happen (the same ones that control the fan speed).

    Leave automatic graphics switching on. D3 will boot up the Nvidia chip no matter what, the Intel 4000 doesn't stand a chance at playing D3 at these resolutions. I played for the first time on my rMBP yesterday and it was fantastic! Also played while hooked up to my HDTV and that was also cool. Can't wait to get further into the game.
    Cheers.

    Nope, you're fine. Computers don't exist to be babysat.

    I got pretty addicted to Diablo 2 back in the day. JUST SLAM IT STRAIGHT INTO MAH VEINS

    Diablo III will run on both the 15" and 13". The 15" can take a lot higher settings than the 13", due to the GPU. Both of them will have the fans screaming and aluminum hot enough to be annoying.

    If you are concerned about temperature and want to reduce it elevation of the rear of the machine helps, as sitting flat on the desk only reflects the heat back to the base of the Mac. You can buy passive aluminium coolers like Rain Designs Mstand or iLap. Most powered coolers are designed for PC notebooks and don't work overly well with Mac`s if at all. One cooler that does work efficiently is the Moshi Zefyr 2, as it`s principle of cooling is specifically designed for Apple portables, by blowing the air horizontally across the base of the computer, however don't expect miracles.

    A cheap USB fan can achieve the same if strategically placed, not as elegant mind, nor as easy to put in your notebooks case :p but they do help to reduce case temperatures.

    You can use software to override Apple`s own cooling algorithm by manually taking control of fan RPM and setting up power profile presets with SMC Fan Control 2.4, or here with UltraFan which allows you stipulate a preset temperature and the software will automatically raise and lower fan RPM`s to keep the system at the predefined temp, which i personally feel is a far more elegant solution. At the end of the day you want to control your system temperature, not your fan rpm`s. For me SMC is now pretty much redundant with the latest release of UltraFan having manual control of the fans RPM, and subsequently i am starting to uninstall it from my own Mac`s. SMC FC is a great app, however although it`s recently updated, functionality is limited compared to some newer apps, equally SMC Fan Control is rock steady stable and a finished product.

    Strictly speaking Apple`s own cooling algorithm works, albeit at sacrifice of increased temps for quieter operation. This has always been the Apple way and is really nothing detrimental to the system, i have one MBP from 2008 all original barring a recent fan change that has an uptime of over 30K hours. The latest MBP`s need less assistance in remaining cool; for some it`s simply disconcerting the heat generated and transferred to the case, although it`s perfectly normal as the aluminium acts as a heat-sync. i have to deal with elevated ambient temperature so at times a software solution is useful. Apart from the passive cooling the Mstands bring they also offer a very sound ergonomic solution. A passive cooler and UltraFan will maximise the cooling, there is little else you can do short of reducing the ambient temperature or the system load. If I know i am going to push a system i will close all apps that are not essential as this can and does make an impact to system temperature.

    High temperatures in general is not overly harmful to your systems, what is far more detrimental is thermal stress, where temperatures rapidly fluctuate by significant margins over a short period of time. Anyone striving for great longevity should look to minimise rapid temperature changes, here UltraFan is your best friend.

    Using a RainDesign Mstand, a Moshi Zefyr 2 and latest version of UltraFan I can reduce temperature by over 20C when transcoding an MKV video file, and that is something worth thinking about;

    • Apple default cooling algorithm 99C - 103C (still on Mstand) fans 4K and escalating :eek:
    • Mstand, Zefyr & UltraFan 79C - 82C fans at 5.8K :cool:

    Recently i have been experimenting with a CoolerMaster Notrepal E1 cooling pad, it has a single very large fan 23CM (9") running at 800 rpm, and most importantly moving a significant 91.25 CFM, this is far more than most other powered coolers i have tried.

    The fan by far takes up the majority of the coolers body, runs slow and quiet.

    As it`s designed for a PC portable i didn't have any high expectations; the cooler runs quiet as in silent, perfect size for a 15" MBP, has USB expansion, single speed with on/off button and lifts the machine a good couple of inch`s of the desk. I chose my Late 2011 2.4 i7 15" MBP, it`s connected to an external display, runs 24/7 and is generally north of 70C (158F) on any given day. Any software solution only results in the MBP doing a fair impression of a "Turbojet" which we all love to loath, as workloads rise and temperatures increase.

    The important part cooling; well as ever with a Mac a mixed bag, the elevation definitely helps versus being flat on the desk. I have little expectation of any cooler reducing a Mac`s internal temperature significantly, what the Notepal E1 was able to do was systematically reduce fan rpm by a good 1K without any increase in internal temperatures, which is a big step forward. With this cooler and a software solution (UltraFan/SMC Fan Control) it`s possible to have a moderate load and a relatively quiet system, and that counts for a lot. The major downside to the Notepal E1 is the size, it`s clearly designed to be "planted" on the desk. when using the 10 degree angle i use a piece of that rubber you can buy for car dashboards, just to ensure the MBP doesn't slip and slide about, just seems prudent with such an expensive notebook perched on the edge of the desk. The Notepal E1 also unusually blows a stream of cool air out of the front to cool the hands which is well unusual, nevertheless not unpleasant on a hot day.

    I still rate the Moshi Zefyr 2 as the best powered cooler for a Mac portable simply due to it`s continuous horizontal air flow, however the pricing and availability make it a tough choice. 1K reduction in fan speed may not sound that big a deal, however if that keeps the Mac below the "Turbojet' threshold then it`s a worthwhile investment for anyone seeking the quieter life :p

    The old adage still applies; it`s easier to keep a system cool, than cool-down an already hot machine. This being said it`s not strictly necessary, equally it`s nice to know that there are options for reducing temperature out there.

    I completely agree with this sentiment. Since buying a Cooler Master laptop cooler, I've seen temps drop significantly (up to 20 degrees C at times). This was my cooler of choice, but I've been tempted by others:

    Wont work, fans are too small, the good thing with CoolerMaster is they generally document the air flow volume and DB level of their product on the box and website. So far the NotePal E1 is the winner as it moves the most air at the lowest volume, there is one other CoolerMaster that can move more air, however it relies on two high rpm fans.

    Air flow velocity is another factor, however in general greater the velocity of air flow, higher the noise output, if you can source a Enermax Aeolus cooler it may have a slight the edge on the NotePal E1

    No need to worry. Your computer is a tool. Use it.

    I use two Standard Issue Pink Erasers under the laptop to elevate the area around the hinge. Pretty cheap but does help with moving air out of the bottom of the laptop.

    Have you tried to set a frame limit on Blizzard games? I think they all support it. Set the limit to about 30-35 fps and your fans will be much more quiet than before. You won't notice a difference in running WoW with 30 or 80 fps.

    Also if you have the possibility you could run the games in Boot Camp where they run faster with less load.

    88 hours logged with D3. No external cooling. No problems so far. The MBP can certainly handle D3.

    Agreed and this is the very point in question, if you are working in areas with elevated ambient temperature, if you are not simply just playing games. Keeping your Mac cooler and quieter is of great value as over time, as internal temperatures rise the Quad Core`s will throttle.

    My systems run significantly cooler, they never approach temperatures that result in throttling so tasks are finished in the minimum time, also as the temperature is stabilised there is minimal thermal shock, resulting in far greater reliability...

    Ummm.. I think it is more likely ___ ..

    Ummm..

    I think it is more likely that YOU will destroy your rMBP before Diablo 3.. Methinks.. :rolleyes:
