Top Tips for keeping your Mac cool under pressure

After upgrading to Lion on my early 2008 15″ MacBook Pro, I started to notice that the computer was hot to the touch. Really hot. So I started measuring the internal temperature of my Macs to see if there was anything to be truly alarmed about.

It turns out that Mac Intel chips have a built-in feature called THERMTRIP that will temporarily suspend the CPU when things get hot, and shut down the CPU altogether when things get too hot. Speculation is that this temperature is somewhere in the neighborhood of 120-130ºC. While my Macs did not reach three digit temperatures, the increase did alarm me. Luckily, as you can see, the temperatures settled down to a normal range after a few days. This is likely due to the machines running a lot of initial tasks like Spotlight indexing of your entire drive just after the Lion upgrade.
Still, if you, like me, are concerned and want to do something a little more proactive than just waiting, here are a few precautionary measures you can take:
iStat Pro Dashboard Widget. One of the first (and lately the only dashboard widgets) I installed is iSlayer’s iStat Pro. This widget will allow you to monitor several of your Mac’s vital statistics, and with the optional companion iOS app, you can monitor your Mac from your iPhone when you’re attached to the same Wi-Fi network. Information reported includes systems various temperatures, and the speed of your Mac’s internal fans. The problem is that as your Mac keeps getting hotter, your fans aren’t spinning faster, something for which we turn to the next tool.
smcFanControl Menu utility for Mac. To manually modify the speed of your internal fans, you can install Hendrik Holtmann’s smcFanControl. For some of the older Macs that are still technically capable of running OS X 10.7 Lion, you may find that they are having some difficulty keeping up at times, and the default fan speed just will not provide the relief required. This menu bar item will allow you to change the minimum fan speed and effectively take control of just how fast your fan will blow. I created two custom settings: a midrange setting at 4000 RPM, and a high setting at 6000 RPM and will turn them on when I see things get a little too hot. I then set things back to Apple’s default levels once things cool down.
Purchase a laptop stand. Proper ventilation is key to allowing your Mac to cool down under normal conditions. Placing your laptop on a pillow or blanket because it is running hot may do more harm than good, especially if you end up blocking the vents that are trying to expel all that hot air. My personal favorite is the Cooling Bar from Just Mobile for $39.95US.  I find it convenient to carry with me and easy to set up.  Just Mobile has other stands for your MacBook as well. And if you tend to keep your Macbook closed when at a desk, consider Twelve South’s BookArc Pro for $49.99 U.S.
Let us know if you have other tips for keeping your Mac cool under pressure, or if you’re seeing temperature spikes under Lion that last beyond the first few days.

Toshiba Thrive Tablet is Pretty by wholesaleeshop

Pretty much everyone in the world has owned a Toshiba laptop at one point or another.  That’s because Toshiba can do gadgets right when they take the time.  We don’t count the Folio as taking time.  But the Toshiba Thrive Android tablet, on the other hand, is shaping up to be one of the better tablets we’ve seen this year.  It doesn’t beat the Galaxy Tab 10.1 onweight or thinness, but on connectivity and in about every other area it looks to outshine about every tablet we’ve seen this year.  Let’s go over the specs first.

The spec sheet is on par with the Honeycomb standard we’ve seen so far, with some big differences in the ports:

• 1 GHz dual core Tegra 2 processor
• 1GB of RAM
• 5-megapixel rear camera
• 2-megapixel front camera
• Full-size USB Port
• Mini-USB port
• Full-size SD card
• Full-size HDMI port
• Wifi + Bluetooth
• 8GB, 16 GB, 32 GB versions, but supports up to 128GB cards.  <—Very nice.
• Android 3.1 Honeycomb

So you noticed all those full-size ports?

Ports Galore

That’s part of what sets the Thrive apart from the rest at the moment.  Yes, the Iconia Tab has a full-size USB, and the Transformer has a full-size USB on the dock, but no one has a combination of all these full-size ports, offering real integration with a home PC and all kinds of portable media.  Since this tablet runs on Android 3.1, you can also expect those USB ports to be worth something with all the added USB host support.  The ports may be exciting, but there’s also the storage to consider.  The Thrive’s basic unit comes with only 8GB ofinternal storage, but the SD card slot supports up to 128GB cards, meaning even the base unit can offer 136GB of storage.  That’s something unheard of in Android tablets to date.

But the good stuff doesn’t end at the ports.  Something else we really liked was the Android 3.1 experience.  It’s about as stock as you can get.  Toshiba says they have gone minimalist on this device, and added a very few bloatware apps.  Even what they have added isn’t really anything you’ll want to get rid of.  The media player app is actually very nice, and the full DLNA support will be a boon to anyone that has DLNA-compatible devices in their home.

Another app is something that’s really been sorely lacking in Android tablets this year, and that’s the file manager.

As you can see in the image, the file manager has a really intuitive interface.  The best part is that it actually recognizes all of the attached storage and lets you easily navigate and copy between them.  +1 to Toshiba for this feature.

And in case that wasn’t enough for you, let’s look at the customization options.  We love user replaceable batteries, and the Thrive brings this option.

And while you’re changing out that battery, why not switch the back cover to a different color?

Toshiba will be offering a number of color choices to give your tablet a custom look, or just change it up any time the mood strikes you.

If you like the idea of a netbook-style hybrid, you won’t be disappointed here either.  The Thrive will also have a keyboard dock with an Android-customized keyboard, complete with Android keys for things like back, home, recent apps, and arrow keys.

It’s a tough world out there for a tablet right now, and everyone has to do something to set themselves apart from the competition.  In Toshiba’s case it appears that they really took their time and did everything right.  We’ll get the final results when the device goes live, which we presently have no date for, but we’d expect it will be this summer.  One last thing.  Where does it fall in price?  The basic 8 GB unit will retail for $429, the 16 GB for $479, and the 32GB for $579.  If you have the cash to spring for a 32GB version with a 128GB SD card you’re talking 160GB of storage on an Android tablet.

Google Android handset uses Samsung’s latest screen technology

We can debate what qualifies as a true 4G phone, but there’s no arguing the $199 Samsung Infuse 4G for AT&T’s network offers the largest display of any phone the carrier sells directly. The 4.5-inch Google Android handset uses Samsung’s latest screen technology, which certainly makes for a large device; perhaps too large for some. But this handful of a handset uses a thin design, fast mobile broadband radio and a speedier single-core processor than what competing devices offer. I’ve been using a review unit of the Samsung Infuse 4G on AT&T’s network for the past two weeks to see if there’s room in the collective pocket for this new smartphone.

Hardware and Design

As soon as you see the Infuse 4G, you can’t help but notice the sheer size of the display, which takes up nearly the entire front of the phone. A small top and bottom bezel holds the front-facing camera, ambient light sensors, speaker and the four standard Android buttons, which are touch-sensitive on this device. Although the display uses a typical 800×480 resolution, the screen doesn’t appear pixelated at all; fonts and icons are smooth. Even at the lowest brightness, colors appear to pop from the screen due to Samsung’s Super AMOLED Plus display. All activities are more vivid and brighter than on any other handset I’ve used yet. The beautiful screen may be too big for Acer aspire one zg5 battery, Asus a32-f5 battery some, but I find it pleasing, thanks to larger text and more room on the software keyboard. The screen can appear washed-out in direct sunlight, but is still very usable.

Software and Performance

The handset runs on Android 2.2, which isn’t the latest version of Google’s mobile software, but few phones are yet shipping with Android 2.3. Samsung’s customized TouchWiz interface hides the bland stock look of Android in a pleasing way. A choice of three software keyboards are included: the standard Android keyboard, Samung’s own custom keyboard, and Swype. A handful of AT&T-branded applications are pre-installed, along with a few from Samsung. Specifically, Samsung’s AllShare app (used for media streaming), Media Hub for video rentals and purchases, and custom Task Manager app are pre-loaded on the device. The Infuse has access to the Android Market, and can also install software from outside the Market; a first for AT&T, which has blocked such “sideloaded” apps in the past.

TouchWiz offers up to seven home screens, and the program launcher is similar to that on Apple iOS devices. Samsung’s browser is fairly standard, but offers a useful brightness setting within the application. The browser experience is on par with any other Android handset at this price and in terms of speed, I found it to perform a slightly better than on the Nexus One handset I bought  Dell xps m1330 battery,Hp dv1000 battery last January. For the benchmark-minded, the Infuse 4G scored 5082 ms using SunSpider (where smaller numbers are better) as compared to 5487 ms on my Nexus One. That’s likely due in part to the Infuse’s slightly faster single-core CPU, which clocks in at 1.2 GHz. The Infuse 4G will generally be slower when compared to a dual-core handset, but only those who have used a dual-core smartphone would know the difference. The processor keeps Android moving at a fast pace when compared to other single-core handsets on the market.
