I'm doing some research for both my future build and my employer's upcoming radiator product. Looking to build a list of most popular radiators according to what people actually buy. Why did you buy what you did? Any information is greatly appreciated.

I work for a company developing some new waterblocks and we're now in the testing phase. As a result of this, I've been spending a lot of time overclocking our 4790k and through repeated BSODs and resets, it looks like Windows is getting corrupted. We're pushing for max speed, rather than long...

I work for a company developing a line of custom waterblocks and we're currently testing some examples with a Devil's Canyon 4790K i7 chip. My job so far has been to boost clock speed so that we can gather CPU temperatures across a variety of blocks but getting any stability above 4.8GHz has...

I'm getting started with embedded systems and have Ubuntu server installed on a Mini ITX board for portability. It has 4GB of RAM and a 1.1GHz Celeron chip. I've since found that it reboots randomly, but often within a consistent timeframe. Just look at these uptime records from uptimed...

I'd like to build a router I can use to learn about pfSense and run my network for a long time. I'm in Ottawa but reasonable shipping from elsewhere in North America is cool. Looking to save money over Newegg and eBay barebones. Looking for Mini ITX (fanless Atom preferred) rackmount...

My friend has a triple SLI setup he's looking to offload. They are 3 identical EVGA GTX580 video cards with full cover AquaComputer blocks. Cards have been used sparingly over the last year or two and never overclocked. EVGA GTX580 AquaComputer full cover blocks $200 / card with blocks, $575...

So my computer has been down for a few weeks while my watercooling loop was fixed up. After cleaning the blocks and discovering the problem, I assembled everything together, but unfortunately spilt some nonconducting coolant around the PCIe slots. I dried it as quickly and thoroughly as...

I have a problem. Since building my computer in 2011, my loop has morphed to include 2 Reserators, 2 GTX470, 1 120x3 radiator, 1 filter, 2 mosfet blocks, 1 NB/SB block and a CPU block. My loop has been plagued by low flow and for the last month has been stopped while I try to sort things out...

I need to do a full service of my loop and I want to reconfigure my MOSFET block connections (or put them back on air altogether). The last time I did this, I used 2 Koolance fittings to make a hard connection -- 1 slot video and 2 slot video -- but as a result of the distance, I had to mix and...

I received a new PSU from Corsair today after requesting an RMA, so now I have an extra. It is shrink wrapped and ready to go for your next build, and should provide enough power to grow in the future. Corsair...

Lately I've been experiencing very strange behaviour on my main Windows 7 workstation. I'm getting completely spontaneous shutdowns that don't show BSOD or even crash dump. Originally I thought iTunes was triggering something but recently I've had a few shutdowns without it running. I'm having a...

My system (i7 @ 4GHz and GTX470 SLI) has always been stellar for SC2 under all conditions (Ultra at 1920x1200) but since this latest update, I noticed that my GPU utilization is never going above 20% and causing low frame rates of about 10 late in large games. Normally the rates drop when there...

Over the weekend I've built a new system as an HTPC but have been unable so far to get past a very annoying random lock up issue. Parts: ASUS P8Z77M-Pro motherboard Intel i5-3330 CPU ASUS GTX550 Ti GPU Corsair CX600 PSU I'm using a CoolerMaster120mm cooler. After rebooting/starting...

I need another license for Windows 7 for my HTPC. Microsoft only seems to want my money if I'm buying Windows 8. Does anyone know where I can get a proper Windows 7 license, maybe from a hidden page on Microsoft's site? Since I have the install media already, I'm only really looking for the license.

My friend just ordered up some GTX580 3GB Classified cards to start an ambitious build, and we want to put everything under water. At first glance it seems that the stock EVGA HydroCopper blocks are the only ones that support these cards. Is that true? Where can we get the blocks only and are...

Has anyone upgraded to 12.04 and tried running Netatalk yet? I upgraded this morning and have experienced nothing but problems getting my server to respond to my Mac. I've tried compiling the latest 2.2.2 and installing from apt-get with 2.2.1 but nothing has worked. I'm guessing that it has...

I'm evaluating my new storage options while my current server fills up, and have to make a decision. I'd like to build a system with about 9 drives in the pool but I can't decide what level of hardware RAID I should use. Since I'll have more than the necessary numbers for RAID 5 (3) and RAID 6...

Hello [H] friends, I'm hoping to probe the collective intelligence of [H]ard to solve a problem that has flummoxed both my friend and I for quite some time. Previously I posted about an issue with triple SLI GTX580 and since then I have some additional information. The initial issue is that...

My mid-2009 13" MacBook Pro has been in heavy daily use since the end of 2009 and the AppleCare is done at the end of 2012. Checking iStatNano, I see charge cycles of 188 and a health of 88% new. Anyone know what rate might allow a battery replacement through AppleCare? Those with...

I have for sale a slightly used OCZ PSU. It was used for approximately 8 months before I moved to a 1kW Corsair unit. I can't guarantee that every cable included is from this unit directly, but there are no missing cables. For a powerful GPU, it will do the trick nicely. Asking $75...

For sale today is a collection of cooling products I have left over. Items are all located in Ottawa, Ontario and they're small enough that I can ship to North America at a reasonable price.PayPal or EFT if in Canada. Feel free to make an offer, as I'd rather see them used than make extra...

I have this pair of Sony headphones Amazon link that broke quite a while ago. The part that broke was the Y yoke that connects the earpad to the headband. It basically broke where you would expect it to break. Since the headphones still work, I'd love to find a replacement part to keep them...

I'm upgrading my internet this week to cable, and currently I have a single coax run from my router/server to the window, where the cable enters my apartment and I have a DIY HD antenna set up now. Rather than double the run, I'd like to just use a Y connector (something like this) to combine...

Local buyer found, thanks for playing. I have an HTPC/portable gaming rig I built with an i3 and HD6770 that I no longer require. Its original purpose was to output 3 independent displays for a music project, and that project is now complete. For a detailed look at the PC, please visit...

I've set my iTunes media library to use a symbolic link to my Ubuntu storage server and I'd like to do something similar so that iPod formatted TV shows are in the proper directory. The trouble seems to be that I'm trying to create a symbolic link from a folder that itself is a symbolic link...

I've been building a few systems recently, and have run into an organization problem. Every motherboard, graphics card and case comes with spare cables, screws and connectors, but where can I put them? I have spare fans, graphics card coolers, manuals and other plumbing parts. Have any [H]...

A friend of mine just pointed me to the Lian Li PC-343B case, and it looks amazing. It struck me as the perfect alternative to a rackmount server unit, like the Norco 4000 series. Since the external bays seem to be 5.25", I"m not sure how practical it is to house multiple 3.5" HDDs. Anyone...

I have a 850W OCZ PSU that I used for maybe 6 months. I no longer use it because I moved up to a 1kW unit when I went SLI GTX470. It's modular, and all connectors are included. Never had problems with it while it was in my system. As far as I can tell, Newegg.ca sells this PSU for $169 new so...

A friend and I have been scratching our heads about why his computer is shutting down when pushing lots of pixels. Within minutes of starting up the Heaven benchmark, it reboots, and this behaviour repeats for other high graphics applications. He moved from a 1kW to 1.2kW PSU, and the...

A few months ago I bought an mATX case from these boards and have decided the time is just about right to fill it with gear. I've decided on CPU and mobo, but the graphics card will require more thought. My initial thought was to use the machine as a portable gaming rig and HTPC. For that...

I have 1 of these monitors, along with a smaller 19" widescreen that I want to replace. Unfortunately the ASUS is no longer available from the main online and local retailers. Before upgrading to 2 of the same 1920x1200 monitors, I'd like to see if someone has one to sell. I'm located in...

I've been fighting a bit of a battle with my GTX470 SLI setup here since adding a waterblock to the second card. After using it on air for a while, I put it on water, where it performed for about 2 weeks before causing my system to stop POSTing. I removed it, the system worked again, and I...

My system uses a mesh filter installed in the case to clean the Feser One coolant as it enters my internal loop and I suspect there is sediment/particles in the fluid that are getting through and causing fouling inside my CPU block. I've already had to remove the block twice to clean it, so I...

My system has decided to not POST any more. I've been running 2 EVGA GTX470 cards for the last 2 weeks or so, cooled with full blocks. My PSU is an 850W OCZ Z Series model, and today I replaced it with a friend's Corsair 1000W unit to see if that was the problem, but it still didn't POST. The...

Recently while doing various upgrades to my workstation and a friend's triple SLI GTX580 rig, I've had to learn a lot about power supplies. I had a few questions, though, that I think other people might have and want to see if we can pull some answers together. I have an OCZ Series Z 850W...

I just installed the a waterblock on my second GTX470 and when I booted for the first time, the card was discovered as "Standard VGA Graphics Adapter." I'm pretty sure the card is seated properly, and the PSU has enough power because I was running it on air previously. I also just installed...

I'm currently using 2x Zalman Reserator 1 passive heat sinks to cool my workstation, and would like to add in a 3rd. They've been discontinued for a while, so if anyone has an older one they'd like to be rid of, I might be interested!

My workstation (specs in signature) is cooled with 2x Zalman Reserator 1 towers, and this week here in Ottawa we've been seeing temperatures in the mid 30 C (85-90 F) which means the ambient temperature is about 31 C. Normally when I do gaming or anything intensive the water temperature hits...

I have a brand new 120GB OCZ Vertex 2 SSD that I'd like to sell. It is brand new in box, as OCZ just delivered it today on an RMA request. Since it is RMA, I'm dropping the price to $150 USD, compared to retail of $200. It's 2.5", with the standard 3.5" bracket included. As shown by the...

I've OCed my 950 to 4.0 GHz with 1.27V and my GTX470 to 725 MHz using ASUS Precision, and now when I play COD4, I get BSOD with reference to "ntoskrnl.exe". I hear that has something to do with the kernel. Below is the data pulled from WhoCrashed and my crash log. Could it just be voltage...
