    I use my MBP a lot with the lid closed and connected to an external display. My desk is an Ikea glass desk and was wondering if I get the mStand and raise it, it will help with the heat?

    The fans kick it really fast and the noise is annoying.

    Or is there another (elegant) solution that raises the MBP and keeps it cool on a desk?

    You could just open the lid once your computer is on and running, the internal screen should stay off and you have less problems with heat. Elevating the mac will of course also help, but it cant prevent heat from building up under the closed lid.

    I recently got an mStand and found the MBP is quieter than when I used it with the lid closed. I haven't measured temperatures so I can't offer any conclusive evidence other than my own impressions.

    You could look into Twelve South's BookArc. It's designed to be used with closed laptops, and as a bonus it reduces your laptop's footprint on your desk.

    I've got a BookArc as well but it doesn't solve the problem of the MBP being nosier/warmer with the lid closed. However, it was a really nice solution when I was working on my older smaller desk.

    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:

    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.

    Just this weekend while scouring the local computer markets i found 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.

    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

    Oh noooo not the plastic flip-legs ... *flashback of numerous plastic flip-legs breaking off my keyboards*. :(

    Well first of all what are you doing that kicks the fans into high gear?

    I do alot of 3D stuff and my fans are in high gear for hours at a time. I have an mStand and keep the macbook pro open. Nothing you buy is going to stop the fans from kicking into high gear if your using intensive applications. Just the let the computer do its thing and it'll all be okay.

    I have a Zalman ZM-NC1000. Works great, reducing my temperature with 15-23 Celcius. I have been using it for three year now and the fans are beginning to make werid noises, so I'm going to shop for a new cooler.

    Possibly the ZM-NC-2000 with a bigger cooling surface.

    Personally i do a lot of research, so have a plethora spaces/tabs dedicated to Safari, same goes for documents, engineering applications, online backup, VPN`s, multiple display`s the accumulated load simply adds up and the fans spool up. I like to work at night when it`s quiet and of course the fans can be a little intrusive, like a Turbojet. In general i span my work across two 15" MBP`s a Late 2011 2.4 as primary and a base Retina as backup and secondary. Heavy Lifting`s done by the Retina; it`s marginally faster, has better thermal characteristics and above all quieter.

    It is possible to reduce the systems temperature by using a passive stand like the Mstand and a carefully balanced software solution, right now i trying a CoolerMaster Notepal E1 (see above) which is delivering some good results in conjunction with UltraFan & SMC Fan Control. The 2011 MBP is running around 65C, fans at around 3K, equally once that Quad Core starts firing on all core`s there is little you can do to prevent the fans spooling up. What i am seriously considering is to buy a high efficiency case fan (tower) bigger the better around 200CFM or greater and install it into a Rain Designs Mstand, i will have the elevation i want and an increased air flow to the base of the system. Just as a note ambient here is rarely below 25C with the AC, without it can easily get to 30C.

    Mac`s have always run hot, the new i7 powerhouses just more so. High temperatures are not detrimental as long as the system is within spec, rapid thermal shock is the concern as will and does reduce lifecycle of any electronic component. If you can keep the systems temperature stable it will definitely help with longevity. I also have an Early 2008 15" MBP (2.4 Penryn) and it has an estimated runtime of over 30K hours, which is not bad considering it has the afflicted Nvidia GT-8600M GPU, and has been absolutely hammered.

    ----------

    I know :p however the flip legs lift the MBP up to an angle of 10 degrees and although there is no noticeable difference temperature, the cooler is more efficient allowing a less restricted path to the 23CM fan.

    The mStand helped with my MBA 13" keeping cool while using the Thunderbolt display. Used to kick the fans into high gear just doing basic tasks, after the mStand is was less often. If you play games or view flash, it isn't going to help much.

    My use case is the same as yours. I've been using the mStand, which does help, somewhat. As others have stated though, don't expect miracles from passive cooling. Still, I absolutely do not regret getting the mStand.
