ThinkCentre A70 (7099) case fan, what size?

Hi,
I need to get some more air flowing through my ThinkCentre A70 (7099).
There's a place for a fan in the rear of the case below the PSU. I've measured it and I think it's either a 92MM fan or a 100MM fan but I don't want to buy the wrong size fan.
I can't find any information about it on any document from Lenovo. There is no information what so ever about a rear case fan for the ThinkCentre A70 anywhere.
Which size is it?
Regards

You might want to use a 3-pin fan with speed adapters, so you can control the amount of air flow (rather than rely on what the BIOS thinks is correct.) I have the precurser to one of these installed with the medium speed adapter:
http://www.noctua.at/main.php?show=productview&products_id=104&lng=en
"3 speed settings for full flexibility
Providing 1600, 1250 and 1050 rpm speed settings via the supplied Low-Noise and Ultra-Low-Noise Adapters, the NF-A9 FLX (Flexibility) can be fine-tuned for superior airflow or maximum quietness."

At what temp will MB start case fans?

I apologize in advance if this is covered somewhere and I've missed it. I did some forum searching for case fans but didn't seem to find anything related to me.
I have a Z77MA-G45 installed in a SilverStone case with two front case fans. Those fans have never started running on their own, but the fans will run if I bump one / "push start" the fan. After playing a simulator on full quality my video card fans were going crazy and it seemed like the air inside the case was pretty hot, but the case fans weren't running. I thought something may be wrong, but then I thought maybe even with the video card fans going full-bore the internal temperature wasn't enough to start the case fans.
tl;dr Does anyone know what governs MSI's automatic fan control? How hot does it have to get in that case before the fans run?

None of your three pin fans can be controled. CPUFAN/ SYSFAN1/ SYSFAN2 are all four pin on Z77MA-G45. Other than on other MSI Z77 boards the fourth pin of all headers is used for control on this mainboard.
Quote from: Z77MA-G45 manual
you must use a specially designed fan
with a speed sensor to take advantage of the CPU fan control
Connect the fans directly to psu and use a manual fancontroler.

Re: What size fan does the HPE h8-1234 use?

Hey, are you sure the h8 1234 wouldn't use an AM3+ cooler? Doesn't it have an AM3+ socket? Sorry, pretty sure mine does and I'm looking to upgrade my fan after upgrading my Video Card and I want one that'll be compatible and fit into the stock case

To simplify your question:
The rear case fan (aka system fan) is a 92mm x 92mm x25mm thick fan. It is a standard 3 wire fan. Do not pick a quiet type fan, as the low rpm will fault your system. You can check your existing fan's speed with CPUIDHWMonitor, fan is FANIN1.
Now the other part of your question:
The rear case fan attaches to the SYSFAN header. Just follow the lead. It does not have anything to do with the AM3+ or LGA 1155/1156 type socket. That is where you have confusion. In general, adding a faster case fan should assist in lowering overall temps in the case.

What size external hard drive should I purchase

What size external hard drive should I purchase? I'm not tech savvy, so please speak slowly. I'm looking at OWC Mini Stack Classic to match my older Mac Mini. Do I need 500 GB, 1 TB or more? Plus, I have to add memory to upgrade to Snow Leopard. How much memory do I need and should I have an expert install it ?
Mac OSX version 10.5.8
Mac mini 3.1
Processor 2 GHz Intel Core 2 Duo
Memory 2GB 1067 MHz DDR3
1 Processor
2 Cores
L2 Cache 3MB
Memory 2GB
BUS Speed 1.07 GHz
Boot ROM Version MM3.1.0081.B06
SMC version 1.35f0
Hard Drive
Format MAC OS Extended
Capacity 297.77 GB
Available 238.69 GB
Used 59.08 GB on disk

Good points raised by all.
In my mini configs - both older and newer flatter model - I have kept their ministack external drive on top of the mini; with 3 or 4 little rubber feet added to the mini's base to give it a bit more elevation from the surface they are sitting on and a bit better chance to breathe. I'm not impressed by the very small air intakes on the bottom and the hot air that often comes out the back or how warm the case feels. Especially in the heat of summer.
I do turn the ministacks on/off as needed (primarily for backups once a week) as they're not entirely quiet and sometimes seem to have a low hum vibration. Nothing crazy. I just like it as dead quiet as possible sometimes. Plus the fan does not turn off even if the mini and ministack drive have shut down. The newer wide & slim model does seem a bit quieter than the older model.
Check through system profiler to see if your system has 2x1GB or 1x2GB. Most likely it is 2x1GB and you'd need to remove both to double your ram. On the off chance it has a free slot; a single 2GB stick would get you to 4GB. Check on the cost difference between the 2x2GB kit and a 2x4GB kit. I have an older core duo mini that functions fine with 2x2GB of RAM and 10.6.8. But, if you plan to continue to use the mini for several more years as a primary machine including upgrading the OS to Yosemite; it might not be a bad idea to just max it to 2x4 8GB. Yosemite really likes RAM to maximize performance.
Along the lines of keeping the same mini and doing upgrades. The biggest speed improvements are made by replacing the original internal hard drive with a flash drive. Of course this is a more technical upgrade, you really need to take the mini apart more and you have to weigh the cost of the upgrades and possibly paying somebody to do them; vs the cost of a newer system which would have a significantly faster processor and other improvements.

Sawtooth Quieting Project: Fan Replacement - Specs on 120 mm case fan?

So I thought I'd look into potentially cutting down the noise from my Sawtooth by replacing the 120 mm case fan. So, I have three (hopefully short) questions on my mind about this:
a) What are the specs on the original 120 mm case fan? All I can see is that it's manufactured by NMB.
b) Would I have to do anything special to get a replacement fan to work? (i.e. getting around non-standard power connectors, etc.)
c) If anyone's tried this before, are there any recommended fans out there I should look into?
Thanks in advance.

That's something I ran into, too. You see recommendations for certain types of really good fans but you cant find them in local stores.
This is what I did to quiet down my noisy Mac(after this thing was running for about half an hour it was just intolerable to be in the same room with).
I replaced the fan in the power supply.This is about the most difficult thing to do but the noise reduction was immense.This is a 80x80x25 mm fan and I put in a Thermaltake I bought at a PC shop.CFM (37)is lower than what was in there but the air coming out is barely warm.
I replaced the case fan with a Coolermaster ( forget the model)that is much quieter too.Look for a 120 mm fan, take the old one with you to check the size/thickness.
Then I hooked the case fan and the CPU fan ( this is a Quicksilver) up to something to regulate the voltage.I'm using a Radio Shack/ The Source power adaptor that can output either 12v,9V,7.5V, etc with a little switch on the unit.
I also opened up one of the PCI slot cover to let a little more air in.
Instead of running the fans at their rated 12v,I use the adaptor to run them at 9v.The noise reduction is dramatic, the unit does not get hot inside ( when I was testing, I opened it up and touched the heatsink every half hour or so, not hot at all).And you can always flip it back to 12V to run the fans at full speed anytime you want.
This is works great for me, it might not work for everyone if you're not comfortable with working inside power supplies ( potentially dangerous, do some reading on this first)or messing with Apple's precious fans.But I'm talking a 2/3rds noise reduction here with less than $50 worth of parts!
I didnt replace the CPU fan ( yet) because the replacement I bought was actually noisier than the stock one.Smaller fans tend to produce the most annoying noise, the larger the fan ,less irritating the sound.Find a local PC store that sells parts and has a decent return policy.Anything 12V will work in a Mac regardless of which sizes you buy.
Decent fans have the specs clearly marked on the box.Dont get too hung up on CFM ratings.I've found that certain fans are quieter than other regardless of CFM and Noise claims and you just have to try them out in your Mac to find the one you can live with.Luckily , we're talking about cheap parts here and the biggest hassle is dealing with Apple's dinky fan connectors. I just cut them off and splice..red to red, black to black.
If I was running major heat sources like 2 Ghz CPU upgrades or 256 MB+ vid cards, I might think twice about under-volting the fans, but I'm not.This Mac is primarily for music production and recording and I need it to be quiet, otherwise it is useless to me.
Dont be afraid to get in there and replace/fiddle with those fans. The results can be dramatic and very pleasing to your ears.

What size hard drive will fit into a 2010 Mac mini?

Hello all,
I am planning to buy a new Mac mini. However I intend to upgrade the hard drive, i.e. buy a 320GB Mac Mini then remove the hard drive and replace it with a better one.
I have my eyes on two Western Digital hard drives:
+ WD Scorpio Black 750 GB SATA Hard Drive (WD7500BPKT)
specs: http://www.wdc.com/global/products/specs/?driveID=905&language=1
+ WD Scorpio Blue 1 TB SATA Hard Drive (WD10TPVT)
specs: http://www.wdc.com/global/products/specs/?driveID=685&language=1
Here's the problem. I figured that being both SATA 2.5" drives, they would have the same dimensions. It's not the case:
+ my preferred choice, the Scorpio Black (with faster 7200rpm) has a height of 9.5mm
+ the Scorpio blue (1TB but 5200rpm, slower than the default drive) has a height of 12.5mm
So I wonder, which of them would fit in the mini? Both of them? Afer hours looking for it, I couldn't find the exact specs and dimensions of the default drive in the Mac mini.
Questions this arises: if the Scorpio Blue fits in, then will the Black be loose because it's thinner?
I just went to my local Apple retail store, the flagship Opera store in Paris. I asked two Geniuses there and neither of them was able to answer my question, including the so-called hardware expert (duh!). They just told me "good question", and advised me to be careful with dimensions indeed because there is so little room in the mini...
Has any of you guys any clue on the subject?
+ any idea of the size/specs of the default drive?
+ any idea of what size drive would fit? Does the new disk have to be the exact same size or not?
FYI I checked the specs of the mini they had on display, and the disk reference is TOSHIBA MK3255GSXF. It looks like a specific ref number for these Apple drives.
Thanks!

6 MONTHS LATER/UPDATE.
I got the the Seagate Momentus® XT 6Gb/s 750GB Solid State Hybrid Hard Drive. Was able to install it myself in the Mac mini; it works great! (now).
My original 350GB was near full and taking almost 5-minutes to load.
Now my computer boots up in under one minute. Big difference!
Apps also snap open quickly, all functions fast and with 8GB of Ram using my computer is fun again.
Note: Initially I just made a clone of my old HD to the Seagate before taking my old HD out. This did make a bootable volume but funky and eventually the mouse clicks took 4-5 minutes to work!?
So I wiped the Seagate clean, did a new/fresh install of my Mac OS onto it and then used the Apple Migration Assistant app to get all my apps and data over - This worked and no funky stuff developed.
It's the best change to my computer in years. Feels great...and besides the features of the fusion-sytle hybrid drive (SSD & regular) I got 450GB of new, extra space...now I can put my work aside for awhile and try out one of these 12GB games!. Rock on.
INSTALLATION INSTRUCTIONS: patience, patience, patience and instructional video at OWC; yet the insides were different, an extra plastic 'cage' around the HD. Just be careful & alert.

How do I fix my case fans??

I have two 80 mm case fans (12v). I was wondering what the allignment of the fans should be. Should These fans blow air INTO the case or should they SUCK OUT the air from the case. I currently use a 350 Watt CODEGEN PSU with a single fan which sucks air INTO the PSU and hence INTO the case. Problem with sucking air into the case is that a lot of dust gets into the cabinet. On the other hand, sucking air out of the case leaves lesser air for the CPU and NB fans to effictively cool the CPU and NB. Any sugestions??
I plan to overclock, but not right now. The temperatures at no load are as follows:
With Side Pannels Fixed - CPU=51 Degrees Cel System=44 Degrees Cel
Without Side Pannels (Open Case) - CPU=43 Degrees Cel System=41 Degrees Cel
Is my comp overheating?
Current Rig Config:
P IV 2.8c with HTT Enabled
MSI 875P Neo-FISR Motherboard (BIOS ver 3.2)
512Mb x 2 Kingmax (MPXC22D-383) PC-3200 CL2.5184 pin DDR DIMMs Running in DUAL CHANNEL
ATI 9500 Pro 128 Mb DDR (AGP 8x / Fast Writes Enabled)
Sound Blaster Audigy Platinum
Pioneer 16x DVD ROM / Sony 52x CD-RW
80 Gb Seagate HDD 7200 RPM
Codegen 350Watt SMPS

As mentioned in the other of your thread, you PSU is weak currently, so maybe when you get another PSU, it should be intaking air to the PSU and exhuast out from the rear.
Just always remember the rule of "Hot air rises and cool air falls" and you'll most probably know where the fans are to be placed. Next, you should always try to keep the same number of intake fans and exhaust fans to keep a good capacity of airflow within the chassis.

Where can I get a replacement case fan for a HP Pavillion 180t

The case fan on my 5 year old HP Pavillion 180t has begun to make noise when running. This is the fan mounted to the back of the case, drawing air over the CPU cooling stack. From what I can gather from the HP support site, this model is no longer supported. I need to know the specifics for the fan in order to find a replacement. I would hate to have to purchase another PC because a $20.00 fan was failing. Thanks

The rear mounted fan is commonly called the System Fan. As a reference, it's model number and pic can be found here. The fan is a 3 wire 92mm x 92mm x25mm case can. Amazon price is lower.

What size should i save my pictures to make a good high def. DVD?

Ok, I am using Elements 10 with Premere 10 to create a DVD high definition movie of our trip to Rome to display on our hi def tv. What I want to know is what size should I save my pictures after fixing them. The JPEGS are usually saved to around 2 mb while the NEF's are saved around 6-11 mb's. I am afraid that the 2 mb files will not retain enough data to show well on the high def TV and maybe the 11 mb pictures may be overkill resulting in long rendering times and larger movie sizes. Anyone have any information on this. Both the Elements 10 and Premere 10 manuals don't address this. The only thing I could find was that they support up to 4086 x 4086 size pictures. Thanks in advance

Hi,
I am not an expert on this subject but since nobody has replied yet, I thought I would give you my current thoughts on the subject so then someone can either confirm it or shoot me down in flames.
If we are talking about a HD TV, they have a screen resolution of about 1920 x 1080 or 1360 x 768 so if your images are greater than that, something has to do some down sizing.
I think that a normal DVD can has a limitation on size of 720 x 480 (NTSC) or 720 x 576 (PAL). To get a greater resolution than that you need to talk about Blu-ray.
The important thing to think about is the aspect ratio. The widescreen TVs are 16:9 and your photos are probably 4:3. If you want a full screen picture without black margins each side then I suggest that you do some cropping first.
I tend to crop to 16:9 aspect ratio (using crop tool) and then resize the image to 1920 x 1080 (using image resize). I use a larger size if I know I want to use pan & zoom effects. I use that size, even though some pixels will be lost, just in case I switch to Blu-ray in the future and it might save a bit of work then.
Hope that helps (and is correct)
Brian

What Size Drive for Media Cache?

Hi there,
I'm about to edit a large project (5TB of 4K RED footage and counting) on a laptop and am intending to use the setup below for disks. Ideally I would have gone for a "4 disk" setup, but I've maxed out my eSATA connections and would have to use USB for anything else. If coincidentally you can see any problems with this configuration please let me know!
Disk Setup
C Drive 750GB (OS, Programs)
3x 2TB Drives in eSATA docking stations (Media, Projects)
Second internal hard disk (Previews, Media Cache, Exports)
I'm intending to install a second hard drive in my laptop to use for the Media Cache. What size/speed drive should be used for this purpose?
Thanks!

Perhaps only that the predominant holy grail on this forum is achieving a high PPBM score, not necessarily edit 4K.
I've worked with 2K and 4K files on very slow machines, and I am not an editor - a systems integrator. It's being done.
Personally, I wouldn't dedicate a disk or a volume to media cache and DB - I believe that money is better spent on the main media volume's speed and capacity. People who have done it on modern (not old) systems haven't reported much of a performance boost. But if you find otherwise, I'd love to hear about it.
In your case, since you don't seem to plan to have a relatively fast main media volume (e.g. an eSATA RAID0), a separate drive for media caching and database may have a performance benefit. The size of it depends on the size of your projects, how complex your project and timelines are, how much rendering they require. Usually even a small disk (under 100GB) will do just fine for the purpose; the current "sweet spot" is around 256GB SSD and 500-750GB 7200rpm mechanical drive.

What size for my ebook?

I am creating an ebook and am wondering what size to make the pages. Someone suggested 6" by 8" in case people want to print it which makes sense, but I don't know if there are other factors, and what is standard.
Any suggestions?

Thank you so much for your reply! I just want to double check - and get your opinion, since I'm forever paranoid. This quote is from Apple Support regards the memory for the build of my iMac:
4GB (two 2GB) of 1333MHz DDR3 memory
Configurable to 16GB, only at the Apple Online Store.
But I don't have to worry about being confined to 4GB sticks - I can go ahead and install what I've bought? - Crucial 16GB Kit (8GBx2) DDR3 1333 MT/s (PC3-10600) CL9 SODIMM 204-Pin 1.35V/1.5V Notebook Memory Modules CT2CP102464BF1339
Sorry - I've just had so many issues in the past, I want to just make sure I have bought the right memory.
Thank you!

What size hard drive?

I have about 5 hours of footage that I need to upload and edit into a 15 min short film. I have Final Cut Pro HD on a G5 desktop, and I'm wondering what size external hard drive would be good for this amount of work?

A hard drive is just that...a hard drive. Bare with connections that connect directly to your computer. Now, if you have a G5 or MacPro, then I'll second Chuck's recommendation for that SATA drive. $150 and yo have 500GB. A G5 will have one extra drive bay that you can install that into and you'll be set. A MacPro has 3 additional drive bays for drives. Filling up your internal bays first is always recommended.
An enclosure is a case to put that drive into...for when your internal bays are full. This enclosure then connects to the computer either via USB 2.0, firewire 400, firewire 800 or eSATA. USB connections aren't fast enough for video, FW400 is only good for DV and HDV, FW800 adds DVCPRO HD and uncompressed 8-bit, and eSATA can get you uncompressed SD to uncompressed HD.
The cheapest and best solution is what Chuck said, the 500GB SATA drive. Faster than FW400 or 800...much cheaper...and it slips right into the computer in about 5 min. But, if you need portability, then look for a firewire drive that you can connect to any computer with a firewire connection.

URGENT !! Where to connect Case FAN's

Hi there.
I just got a new Lian Li PC-v1000 Tower, equipped with 2 1200mm FAN's.
One has a standard 4 pin's power connector
One has a 3 pin power connector (With sensor).
My Motherboard (MSI-K7N2 Delta), is equipped with a CPU fan (used), and a "System Fan" (also used by the Noth/South bridge chipset) connectors.
My Power Sypply, an Antec true power 480W, is equipped with 2 standard 4 Pin's power connectror dedicated to FAN's.
I connected one of my two "tower" FAN's, but ...
where to connect the second 120 mm tower FAN ?!?
I have no place anymore on the motherboard, and this tower FAN is a 3 Pin(with sensor) connector, that I can't connect to my psu !!
Any idea ?
P.S. : My psu is also equipped with a 3-pin fan signal connector ... that should be connected to my motherboard ... but where ?!?
Thanks !

i would not use those two 1200mm fans as the case might fly away
i dont recommend putting those case fans on the motherboard without checking how much power they use as its possible they will burn the motherboard.
go out and buy a fan connector adaptor which you then connect to an ordinary molex contact.
i have seen adapters that would work with those "fan only" connectors.
i use my case fan on the fan only and its enough for me however it may not be enough for everyone so keep an eye on your temps
about the psu contact.
you can change the heatsinkfan to a zalman nb47j (northbridge)
i read a review where that passive heatsink performed better than the active heatsink on a asus motherboard did.
that would free up one contact.
dont do it if you dont know what your doing.
