This review is from: Intel BXSTS100C Passive/active combination heat sink with removable fan
Pros: This heatsink is quality and VERY heavy for its size (about 1LB); the fans are quiet at 1k RPM (unfortunately the BIOS here is buggy and I do not have any way to make it spin at full speed since Linux does not have an hwmon module for my board).
This seems to provide some cooling for the VRMs next to the CPU as well - this is nice.
Cons: The fan is not "Removable" per se; you need to remove the heatsink from the board first and then remove the screws mounted at the bottom of the heatsink.
Other Thoughts: I haven't had a chance to test this entirely, but this is by no means the kind of fans/heatsinks Intel makes for their desktop CPU. This is quality stuff.
Note that this will NOT fit an i7 LGA 1366 socket without perhaps a third party mounting solution. Even then, you would probably be better off getting a bigger heatsink as this seems designed for the Xeon 5500s which run cooler as opposed to the i7.
Using two of these with dual E5520s (80W each)
Pros: To be honest I've only had this for a few weeks, but it seems rock solid, not making any strange noises from the power regulation, and is overall just heavy. The 140mm fan cools off the whole chasis - which is good. for those people complaining that it does not have an exhaust: When you have such amount of air coming in such a tiny space, you don't need exhaust because air is forced out the sides.
Running a Dual E5520 system (was worried it would not work), but functioning fine and voltages are rock solid.
Cons: Fan is apparently brushing against something or is broken. This means I will need to choose between downtime (RMA and all) and voiding the warranty by opening this thing and replacing the fan (or placing whatever it's brushing against further away). There should be a way to replace the fan without voiding the warranty.
Flimsy SATA power connectors. One of them already broke. The plastic on them is so thin and fragile it's amazing. Considering everything else is very heavy and solid, it's pretty absurd.
Also attached PCIe is not necessarily welcome, as this is supposed to be "modular". Cables are VERY stiff, pretty much defeats the point of manageability, but this does not leave a Frankenstein of cables in my case as my other PSU does.
Other Thoughts: It's modular so it's good. I assume I can get replacement modular cables. Also there are WAY too many PCIe cables and not enough SATA cables.
It's nice and heavy though.
Pros: This is my first time buying a Supermicro board and I am very impressed with everything. The packaging it came in was plain and simple. The manual was robust and the six SATA cables are 18" instead of 12" inches.
Unlike many of the i7 boards I've seen (Granted, this is E5500 and not i7), this one has its PCI-E slots spaced normally. This means that one is able to use two passive PCIe video cards without them overheating, although this is probably due to the lack of a need to support an SLI bridge (which this board does not support). Onboard audio makes it perfect for a desktop system as it eliminates the need for an addon card. It's also got two legacy PCI ports.
The manual is written very well and in proper English (and not some poor translation).
Cons: For this price it would be nice to give some more SATA ports or SAS ports via a second controller (Intel ICHR10 can *always* only give six ports). No legacy IDE (it's a good thing I just bought a SATA optical drive).
Also, this device has two sensor chips, one of which is not supported by Linux (at the time of writing) which means that hardware monitoring will be a problem (I have difficulty installing the Superdoctor software in Linux, although it is officially supported).
No overclocking, but this is expected from a server board.
Placement of the ATX and EPS power connectors are horrible for my case and have already caused one SATA power connector to crack (because one of the drive bays in my case is located about an inch from that area).
I wish the specs would state more clearly that you MUST use both processors to utilize all the RAM slots.
This uses AMI BIOS and has serial redirection as an option. However it is disabled by default, which means that on a bios reset
Other Thoughts: (cont.) you will need to attach it to a VGA display in order to manage the machine. This seems rather foolish as serial connection is usually considered a failsafe. I do hope they change this in later revisions; althout this is the second machine I am using with such a BIOS
This board will take regular *Desktop* memory (UDIMM, or unregistered memory) and you do not need to buy ECC RDIMM for this.
The heatsink mounts on this board (and apparently on all 5500 boards) are NOT compatible with i7 heatsinks (with the plastic push pins). These use *Screws* and the holes are too small for the plastic pins.
Also, you MUST have two processors installed in order to use all six memory banks. This is due to the memory controller being integrated into the processor, and the fact that the 5500s use two QPIs, one to access its own memory, and one to access the memory of the second CPU. This of course makes it faster, but it does bring about that limitation.
