Mac Pro :: Mac Pro With Heat Sink?
Oct 3, 2008So, at my college, some departments own Mac Pros; one of them decided that they would like to fit the Mac Pro into a smaller space, so they cut ALL the handles off, which of course removed the heat sink, so the computer overheats. Long story short, the computer ended up in our tech trash, and I took it, DUH it's so beautiful (even without the handles). How can I make this computer usable? Would a water cooling system do it?

Apr 23, 2008What is your heat sink temp when the cpu is running hot, like 90+ degree C?
I recently performed the excess thermal compound removal procedure. Now I am worried that my cpu and heat sink are not in 100% contact, due to the very small amount of paste applied.
My heat sink sits at around 50C under normal load (cpu temp ~ 60). But at high load, cpu up at 90+ C, my heat sink is still at around 50-60C. Is this normal?
Mac Pro :: Could I Maufacture, Hack Together To Sink My Own Heat

Jan 20, 2009At my university there was a flood during christmas break while I was away, and my office had about 8 inches of water in it. When I got back, I saw the damages and was quite sad to see my mac pro filled up with dirt and debris.
So I cleaned it out and tried to boot it up and amazingly it works almost perfectly...in fact I am typing this on that mac pro. The only damage is that the fans now run at 2500rpms all the time.
So Here are my temps from iStat. It seems like maybe the sensor for CPU B and the north bridge are messed up. Anyone have any experience with fixing/replacing those parts? I am wondering if my diagnosis is correct and what is the best way to fix this machine.

MacBook Pro :: Having Heat Sink - Boot Up Temperature From 20 - 130 Degree
Jul 13, 2009I Got a 13 inch MBP and gave my 13 inch aluminum MB to my dad. However i noticed something with the new MBP i got. A)After installing istat pro on both machines only the older MB shows as having Heatsink A and B, the new MBP shows as only having Heat sink B, how come? The aluminum MB on boot up has all the temps (CPU, Heat sinks, HD and so on) going around 20-30 degrees FH, yet the MBP is coming up with 90-130 degrees FH. After 1 hour use the MB has all reading between 28-48 yet the MBP has all readings between 90-140 degrees FH. Both kept in the same room, doing the exact same thing (running safari, same site). I just dont want the nightmare i had with the MBA where i had to return it 3 times because it would over heat and crawl when doing anything slightly intensive. Mine are:
HD MACINSTOSH 83
CPU 131
ENCLOSURE BASE 90
ENCLOSURE BASE 2 90

View 4 Replies View RelatedIMac :: Upgrading Graphics Cards,ram,and Processor?
Sep 12, 2010 I'd like to start by saying excuse the stupid questions, I'm still very new with using macs. I'm a long time PC user, but I've recently made plans to replace my PC with an iMac. Specifically a 21.5" with an Intel i3 processor. This mac comes with 4gb ram, and a Radeon 5650 HD graphics card.
Now I'm a fairly big gamer, and I like my hardware to be as high-end and up-to-date as possible. If I were to plan on upgrading the graphics card, ram, and processor, could this be easily done at home?
I'm asking because of the unusual structure of the iMac. i.e. the lack of tower, and all the hardware being merged with the screen. I'm assuming it would be a lot easier on a mac pro because it actually has a tower that I can easily open/customize.
Lastly, granted that the above is possible, are the generic graphics cards, processor, and ram chips compatible with iMacs? Or would I need to buy a special iMac compatible version from an Apple specialist shop?

MacBook :: Replacing C2d Logic Board With Cd Logic Board Cause Heat Sink?
May 13, 2008so i've got a system with a fried c2d board. i can pick up a cd board for $150 plus shipping which is good for me. to find a comparable replacement, i'm looking at ~350 and i'm just not feelin that price as im on a budget.
i'm not concerned about the speed decrease as im just trying to get this thing rebuilt.
i understand that there are different heatsink assemblys..vertical vs horizontal. however, i do not know how to tell the difference and i am also unsure whether or not my c2d heatsink will work on this board i receive.
the logicboard possess a t7300 c2d and model # is 820-2279-a, it appears.
i cant find anything on that model, except for on ebay.
and i totally cant find the serial number on this macbook. under the battery on the tray has no serial number listed, and i've read through this documentation [URL]
Desktops :: Graphics Card Heat Problem: Radeon HD3870
Jan 29, 2010I'm worried about too much heat and wearing out fans in both the card and my Mac.

MacBook Pro :: Looking For Current Graphics/processor?
Apr 13, 2010If the 13" isn't updated I may get the current version...but was after some advice about the graphics card/processor (I realise I'm probably using the wrong term).
I'd read that users have to log off to switch the graphics option when using the mbp for heavier work.
Can anyone provide an idiot's guide on what this actually means? How often it has to be done, for what tasks (video editing etc) and how long the switch physically takes?

Moving Back To A Mac Pro / Processor And Graphics Options
Apr 11, 2012I have just finished a seven month fiasco working with a refurbished 3.4 GHz i7 mid-2011 iMac, with the Radeon 6970 graphics card. I had originally purchased it to replace an early quad core 2008 Mac Pro. I had the iMac hot-rodded by the OWC folks to include a Mercury 480 GB SSD and eSATA port. That story involves multiple issues with failed components and a complete inability to install bootcamp, which was needed for work-related software that did not play well in a virtualized environment. So now, with the latest iMac hardware failure (Fire Wire port), I have thrown in the towel and will be going back to Mac Pro. (Takes deep breath.)The iMac is currently being used for work, my second job as a part time pro photographer (Photoshop, Aperture), some videography and transcoding and occasional gaming.I'm looking to hit performance marks for processing and video similar to the i7 and am willing to consider refurb or pre-owned machines. New 8 core Nehalem and 6 core Westmere machines are outside my budget. Definite upgrades I intend to add are:
a. 512 GB SSD as primary drive for OS X
b.256 GB SSD for my Bootcamp installation
c.12GB RAM
d. 2 Seagate Momentus XT 750 GB drives in RAID 0 configuration
So, my questions are
1.For real world performance, particularly with regards to my photography work and video, what core processor combinations (going back to 2008 or 2009 used machines could be considered) are likely to yield EFFECTIVE processing power close to the iMac i7? Among recent vintage machines, it seems that a quad core 2.8 GHz would be reasonably close, but I find it's difficult to translate Geekbench results into my needs.
2.I'm having a real hard time with my video card options. It seems that potential choices include the 5770, 5870 and 6970 cards.I'm not overly concerned about the price differences, but would like to find the best performance/value combination, given my needs.

View 8 Replies View RelatedIMac :: Which System Produce The Less Heat?
Sep 28, 2010I'm planning to buy a new iMac in the next week but I'm looking for the one that will produce the less heat so that will make less fan noise. I'm only using it to watch YouTube and play World of Warcraft. Anyone know which one will produce less heat, i3 or the i5 or even the i7. Budget is not a problem. I prefer to pay a little more if I know I will have less fan noise so less heating. Anyone maybe have different model at home or at the office and noticed a difference between all the models ? Maybe it's more a size question between the 21.5 and the 27 inch iMac and less a cpu question ?

Mac :: Heat Power In IMac Vs. MacBook Pro
Dec 23, 2009Maybe someone can help me understand this a bit better. I have a MBP with a 2.16GHz CPU. I think it's about 2.5 years old. It has the ATI x1600 GPU. My dad previously had an iMac G5 2GHz but now has one of the new iMacs at 3.06GHz.When running iStat, I can notice an obvious difference in the CPU temperature. I don't think my MBP runs less than 120 degrees idle, while the iMacs were easily under 100. I haven't seen the new iMac while doing CPU-intensive tasks, but the old iMac never got above 140 if I'm not mistaken.As I'm encoding video on the MBP for a DVD using iDVD, it's getting up to 187 degrees. The CPU is using about 125 percent of my processing power -- 200 percent max if you didn't know. The temperature is the same even when HandBrake gets up to about 190 percent of processing.

Nov 29, 2010I have been researching this and I have came up with no answer. There are note book heat spreaders available [URL]/Product/Produc...82E16835207003 and I was wondering if it will fit in an iMac. Yes I have looked to see how cramped up it is in the memory slot, but I found on the sunbeamtech website that the thickness of the total heat spreader is only .2" at the opposite side where the memory plugs in at. Also I found out the the thickness of the copper on the heat spreader is only .4mm thick which is very very minimal. I have just purchased one of these to test out with the 8GB ram I just purchased for $120 from newegg with a $20 mail in rebate

Mac :: IMac 27 - I5 Vs I7 Heat Noise & Power - 1200VA UPS
Jun 4, 2010I am almost 100% that an iMac 27 is my target, (not quite discounted the MP but lack of remote without extra is actually a big factor).I would prefer the internal HDD bays and such forth, but I've had a MP before and as I have some ext FW its not a deal buster. The imac looks stunning, has simplicity and a nice big screen.My only real questions are (with it being on top of the desk); what's the noise and heat like for the i5 and i7 models? I'd like to get thoughts on both.For my uses an i5 has enough oomph, but the i7 would be nice (just speed up those transcodes etc).Is there a huge difference in the power draw on these machines (I have a 1200VA UPS).

The processor I would like to use is a Intel Core 2 Duo Mobile T5750 processor, which would give me 2 additional cores as well as a small speed bump from 1.83 ghz to 2.0 ghz. I figured compatibility should be fine considering the FSB speed (667 Mhz) is the same. Has anyone tried this? Can anyone tell me if this will work for sure?
