This review is from: powercom BNT-1500AP 1500 VA 900 Watts 5 Outlets UPS
Pros: The power in my area is really, REALLY terrible. The power has the bad habit of turning off for a few seconds and then coming back on, as frequently as every few weeks. This UPS has saved my new computer numerous times from being taken down. I have even heard the UPS switch to battery mode and then back when I didn't think there was a power anomaly, only to deduce that there was just some ripple or something to that effect. There are lots of outlets, and the unit can run my high end computer for a while before dieing.
Cons: It's poorly shielded electrically, so it buzzes really loud when it's in battery mode. This is almost a Pro, though, since it makes it more obvious that a power event is occurring so that you can shut down the computer safely in case you didn't hear the alarm.
It's heavy, but that's lead acid batteries for you.
The big thing, though, is that it heats up while in regular use. The engineer in me can't help but note that that energy is coming from somewhere, and that that somewhere is almost certainly the wall outlet, and in turn my pocket. It's a small price to pay for protection, though.
Other Thoughts: It seems really dumb for me to have a large unit that takes AC and rectifies it to charge a battery, so that in the case of a power outage I can take the DC from the battery, invert it to AC for the PSU of the computer, then rectify it back to DC for the internal components of the computer. When will some company make an integrated PSU/UPS that skips all of the inefficiencies of all of the inverting and rectifying and just rectifies the wall current once and is done with it?READ FULL REVIEW
This review is from: Prolimatech Megahalems Rev.B CPU Cooler
Pros: This heat sink is huge. It is sleek. It moves a lot of air, and with it a lot of heat. I'm running the standard push/pull, and managed to get 4.2 GHz on an i7 930 stable (although this admittedly required using outside air while it was cold outside, ~0 C). I even got 4.4 GHz to run for a few hours under similar conditions.
Cons: I will temper my success story by stating that I have had less spectacular results when OCing using ambient air. I can run 3.8 GHz without danger of CPU throttling, but I worry about long term effects on my system. I have mounted the heat sink several times using the supplied thermal compound, opting out of a 3rd party compound on the theory that the aluminum based compound that Prolimatech ships will interface better with the aluminum of the heat sink. I am questioning this theory. If I get a 3rd party thermal compound and it substantially improves my results I will upload a followup review.READ FULL REVIEW
This review is from: Scythe SY1225SL12H 120mm "Slipstream" Case Fan
Pros: I've had two of these fans on my heat sink in push/pull configuration, and I've been able to get some good overclocking. While my build is loud, it is not deafening, and I easily sleep in the same room as this computer, even while it runs at 100% CPU, with the side panel removed. Noise is very manageable.
Cons: Not silent? But if you want a silent fan with this kind of performance then take out your faerie dust and sprinkle a little bit onto a sample of unicorn horn, then let it cure under the full moon. If you have difficulty procuring these items, settle for less performance or the muffled whoosh that these fans produce.READ FULL REVIEW
