  • CaseLabs S8 Build - “Brutus” - Many months of passive ordering and building on the weekends.
    I started conversing with the author of SIV on the Corsair forum many years ago. We still chat on occasion, usually when he adds a new feature he wants to test on various systems. When I got into Aquacomputer devices, I helped him add support for them. The code is way over my head but I can try the beta versions and report what works and what doesn't until he nails it. If you are interested, you can find SIV at... Source: 11 months ago

    Http://rh-software.com/ hwinfo got nothin on this It way more information in a way more condensed form Maybe not everyone's tea but its really good too. Source: 11 months ago
  • F*ck acrylic tubing
    I got fed up with Corsair back in the Link days and have been using a program called SIV to control my Corsair PWM and RGB controllers for years. SIV (not Gigabyte's SIV) is a system monitoring program similar to HWINFO but more expansive. The author of SIV got fed up with Corsair's buggy software so he reverse-engineered their protocols and added support for many Corsair products to SIV. SIV is extremely... Source: 12 months ago
  • There will be no success here... rip my sanity
    Icue doesn't "block" other applications. It just shoots out polling requests like a drunk soldier with a machine gun, with no regard for other polling requests. The annoying part of this is that the author of SIV was helping Corsair improve their code and showed them how to properly implement the polling mutex, which they did in the later versions of Corsair Link. When they rolled out Icue, they decided that the... Source: about 1 year ago
  • HP Zbook Studio G5
    I am not sure why it says `0x0000`, which implies that the ROM is not being read at all. This is the case regardless whether I pass in a ROM file or not. It might be worth noting that I had a lot of trouble extracting the ROM and managed to do this on a native Windows 11 install using System Information Viewer. Source: about 1 year ago

  • I NEED HELP! How can I fix this?
    I use an app to check system temps: OpenHardwareMonitor. Some people like SpeedFan, does most of the same stuff. Source: over 1 year ago
  • Question - Are the loading times supposed to be this bad right now??
    That's not super common (but it does happen ofc). It might be worth running a tool to scan the drive and take a peek at the SMART data. I typically use Speedfan https://almico.com/speedfan.php. Source: over 1 year ago
  • Computer has come back from a repair shop wiped and is missing A vital app I used to control fan speeds and I cant redownload it. Any alternative apps?
    You'll get better gpu support from Afterburner, but if you have a weird chipset or an incompatible fan controller, good old SpeedFan still has a few tricks. Source: over 1 year ago

  • Computer Software for me :)
    Speedfan Freeware gives you some info about your temps, but its mostly used to set up your custom fan control, such as increasing rpm of your front intake fans when temp of GPU and/or CPU reaches a certain point and much more, how much you can do with it depends on the fan controller chip that is used on your mainboard, so you mileage may vary.
