if it is a 2,1 there is another screw joining the front fans with the speaker, you cannot remove the fans without removing it first. Also the Heatsink cover is magnetic. If it is a Special Request dual xeon 4 core 3 ghz model, the cpu heatsinks are soldered to the CPU's, all a PITA to remove, you must unscrew the Heatsinks and then twist them to break the solder joint, do not pull up or you can break the motherboard. Also the CPU B temperature sensor plug is left to the CPU not undet the memory cage. All people think they are exactly equal and the functionally are, but there are some construction differences. Great video by the way.
I forgot: Special Request MacPro2,1 3ghz soldered heatsinks have a rised part in the middle with touches the CPU and a square metallic gasket around it. Usually I apply thermal grease on the CPU but on those It is better to apply it on the heatsink. The gasket is kept in place with a special transparent grease too.
The side screws for the memory housing::: mine had a very tight one that actually had its threaded chassis post start coming out. I shoved needle-nose pliers under the housing to hold it while I removed the top screw. There was red Lok-Tite on them. The 3,1 is easier to disassemble than the 1,1 in that you can remove the cpu cover and the front fan assembly MUCH easier than the 1,1...
In mine there are 4 screws holding down the ram cage + 2 on the bottom. The fan on Ram cage slides in the cage, so you can remove the cage. I have a chipset heatsink which needed to be removed because I can't unscrew CPU heatsink (there is not enough space to use extension for screwdriver.
Hola t escribo desde Panama y la pregunta es la siguiente: tengo una Macpro Mac Pro A1186 y le salio luz roja de diagnostico en la de CPU A y CPU B, ya se le cambio Power Supply, bandejas de memoria, memorias, tarjeta de video dando el resultado de que es el Logicboard o eso pienso yo. Lo que deseo saber es si sabes coo reparar este board o si es otro asunto y me puedas ayudar a revivir el equipo. Mil gracias, en espera de tus comentarios.
Hola, retomo el hilo por si te pudiera servir. Amigo, si te encienden los LED rojos de diagnóstico en la de CPU A y CPU B como díces, si son los LED: Led 3 (en Rojo) CPU B halts on an IERR (instruction error), Led 4 (en Rojo) CPU A halts on an IERR (instruction error) - Si son los LED: Led 5 (en Rojo) CPU B OT (CPU B is over temperature), Led 6 (en Rojo) CPU A OT (CPU A is over temperature), lo que nos lleva a pensar que pudieran ser los 2 procesadores (2.8, 3.0 ó 3.2 GHz según sea tu caso, a veces se fríen porque les exigimos demasiado en climas muy calurosos, o la pasta térmica ya es muy vieja y no conduce bien el calor a los disipadores, etc. Busca el manual de servicio (no el manual de usuario aunque puedes descargarlo también) en Google, búscalo así: "Mac Pro early 2008 service manual" y de seguro lo encuentras, espero que hayas resuelto tu problema o que lo puedas hacer pronto, saludos desde México!!
No, the ram cage mounts and a few other things are different, also the memory trays on the 2008 are not in the same orientation as the 2006, so I’d assume no
Hola e visto tu imagen. Y no se ingle pero tu computadora es igual a la mia lo que quiero hacer es cambiar los elementos que remplasastes, 2006-2008. Te agradesere si me lo envias por tu pagina de youtube. Muchas gracias es lo unico que se puede cambiar.
This is an extremely thorough demonstration.

Where is this screw
The side screws for the memory housing::: mine had a very tight one that actually had its threaded chassis post start coming out.

The 3,1 is easier to disassemble than the 1,1 in that you can remove the cpu cover and the front fan assembly MUCH easier than the 1,1...
Thank you, sir. 🫡
In mine there are 4 screws holding down the ram cage + 2 on the bottom.
The fan on Ram cage slides in the cage, so you can remove the cage. I have a chipset heatsink which needed to be removed because I can't unscrew CPU heatsink (there is not enough space to use extension for screwdriver.
I have a 3.1 that gives no signal to start, but the fans rotate normally. What can be motherboard or power supply?
Nice video
Nice work
at 3.46 i cant get that piece out it come out on the right side but the left side its like somethings holding it down how did you get it out ?

Hey bro do you know where can i get a logic board for sale for this 2006-2008 version mac pro A1186
I'm selling both of mine on eBay
How do I take out the IO shield?
Where did you find that extension tool?
he purchase 6 screws and attach all of them togeder XD
Been stuck taking out the front fan housing
can you place a motherboard from the 2008 model to the 2006 mac pro ?
No, the ram cage mounts and a few other things are different, also the memory trays on the 2008 are not in the same orientation as the 2006, so I’d assume no
@@flippercomet5002 Yes it is true. It is not worth the effort since we can find a read one for cheap
