CTV Posted May 1, 2013 Share Posted May 1, 2013 Hey guys I owned a H100 which I sold along with my old graphite grey 600T. I owned 3 in total: one was the original, and the other two were replacements. All of them were from completely different batches, yet all of them had the same or similar issues relating to the built-in fan controller. I am thinking of getting either a H80i or H100i, but as you can imagine, I am sceptically hesitant to take the plunge, especially after issues with buzzing / grinding pump noises, completely dead or partially dead (some colours) waterblock LEDs & high pitched squealing / buzzing / whining fans included as part of the package. Not to mention numerous (all unsuccessful) attempts to get a working older generation unit. My confidence in Corsair is a bit low right now - sorry, no hate here, just my honest opinion. I have a few questions/concerns: 1.) Firmware version 1.05 is supposed to fix the grinding pump noise. How successful was this update? Did any H80i/H100i owners still report this issue after the firmware update to 1.05? 2.) Were there higher than normal (compared to the older H80/H100) reports of leakage with these newer generation kits? I somewhere read one guy's H80i or H100i popped in what I would describe a mini explosion. 3.) What is the latest status regarding reports of busted waterblock LEDs? A lot of people reported faulty LEDs straight out of the box or a few weeks after initial purchase. 4.) I found extract quoted by Corsair on Custom PC Review's site while reading up some reviews: "Beginning in late December, all H100i and H80i units have been shipping with PWM fans which have resolved the issues that people were having with buzzing. We have a fix for people who received earlier production units, which should be available in early February. This fix will include the new PWM fans and a firmware update..." 4.1) After reading a sticky on the Corair forums, I would assume the newer / revised fan part number is: CO-8950002. Is this part number correct and in fact the newer revised fans that is supposed to mitigate these high pitched squealing / buzzing / whining noises emitted from the fans? Do they actually work? 4.2) How would I be able to identify which batch (lot code) and newer actually comes shipped with these newer revised fans? From which batch and up? Do the batch numbers run ascending from a lower batch number to a higher batch number? This is really important to get the right batch for me as I wish to get a working unit from the word go, I really do not wish another incident which would be the 4th unsuccessful attempt should the new unit also go south on me. I do not live in the US and simply cannot afford to wait weeks to ship lets say newer fans from the US to my country, especially if the unit is brand new, and as mentioned, I already had bad luck with 3 other older H100 units 5.) This question may sound stupid, but if 2 fans are set up in a push/pull configuration through a rad or heatsink (CPU), does is effectively increase, perhaps even double: (a.) the static pressure and (b.) the CFM airflow when compared to a single fan? I need to know as I am trying to calculate airflow and potential pressures inside my chassis to ultimately achieve a slight positive pressure Apologies for the long post any many questions but would highly appreciate some feedback.

DWreck Posted May 1, 2013 Share Posted May 1, 2013 I have a few questions/concerns: 1.) Firmware version 1.05 is supposed to fix the grinding pump noise. How successful was this update? Did any H80i/H100i owners still report this issue after the firmware update to 1.05? Answer: It was made for some users that were experiencing the issue, it doesn't mean that it will work but it should for the units that came with the noise. As for me, it caused it. But I didn't have the issue before, I was recommended to upgrade to it do to another issue, and had to RMA 2.) Were there higher than normal (compared to the older H80/H100) reports of leakage with these newer generation kits? I somewhere read one guy's H80i or H100i popped in what I would describe a mini explosion. Answer: These were very rare, and most likely caused by Shipping to a Retailer. They do not leave Corsair if they are broken or not working. 3.) What is the latest status regarding reports of busted waterblock LEDs? A lot of people reported faulty LEDs straight out of the box or a few weeks after initial purchase. Answer: The Waterblock problem is uncommon but the LED Problem is random for now. It seems to differ from batches, some come White, Blue, Purple, and Yellow-ish when set to the "White" setting in Corsair Link. Others just die out sooner rather then later. But the odds of getting one that wont suit your needs are low. 4.)

I have not had the old version, but considering the fact they are saying they are coming with PWM fans now that means the old ones were 3-Pin fans. This would be the cause of the Buzzing, because they spin at max RPM. PWM fans can be controlled so they wont make the Buzz sound but spinning them at max speed might bring that back just so you know. You could never spin them at max speed anyway, you will never need to, even in Prime 95. If your buying it from Corsair or Newegg and possibly Amazon you will get the PWM fans. Simply because they are always receiving new stock so the old ones are long gone. 5.) This question may sound stupid, but if 2 fans are set up in a push/pull configuration through a rad or heatsink (CPU), does is effectively increase, perhaps even double: (a.) the static pressure and (b.) the CFM airflow when compared to a single fan? I need to know as I am trying to calculate airflow and potential pressures inside my chassis to ultimately achieve a slight positive pressure Answer: If by 2 fans you mean 2 on one side and 2 on the other equaling 4 then not necessarily. Here's what I can say it will do. It will allow the 2 Fans Pulling Air through the Rad Fins to Catch the already High Pressure Air Flow coming from the 2 Fans Pushing Air through the Rad Fins to effectively Cool the Rad at the least of 1.3X over the effect of just using 2 Fans. As for the Pressure I can not say for sure. DWreck Link to comment Share on other sites More sharing options...

Should it be connected to exhaust out of the back of a case, will the airflow and air pressure exiting the case be the same as one single fan or be higher/more to a certain degree and by what degree?
