The new CORSAIR K95 Platinum XT looks to be a good option based on what you're currently using. It comes with 6 programmable dedicated macro keys, PBT double-shot keycaps, and a very comfortable padded wrist rest. Available with Cherry MX Brown switches, most similar to your Romer G's, but you also have choice of MX Blues or MX Speeds. If you have existing Corsair DIY components in your build, it will use the same iCUE software for programming the keyboard. Feel free to let me know if you have any questions.

If the Corsair H100x is available in your region, that would be the option to go with for a 280X. I have the same case with the radiator mounted in the top, and provides sufficient cooling overall for CPU and GPU.

If you're looking for a quiet AIO solution, I recommend going with the H100i Pro XT. You have options for Zero-RPM fan mode when your system doesn't need maximum cooling, and you can setup custom fan curves based on pump temp and not CPU package which will fluctuate significantly more causing the fans to constantly ramp up and down. The H100i Pro XT is compatible with your AM4 socket, and should be more than sufficient for cooling the 3600X, even if you decide to overclock it in the future. Let me know if you have any questions.

Definitely compatible and a solid choice for the 9900K. Let me know if you have any questions about the unit, and I can help you out.

Looks like you did all the basic troubleshooting steps, and the pump will need to be replaced. I would recommend not taking the unit apart as you probably can replace it under warranty. Those coolers came with a 5-year warranty, so you might still be in the period depending on when you purchased it. You will need to put in a support ticket on our website, and one of our Technical Support agents can help you out: https://support.corsair.com/

The 38.5-40C you're seeing in iCUE, is that for the H100i Pro XT cooler? The cooler temp won't fluctuate as much as the CPU core package, and is normal for it to be significantly lower. One of the benefits to connecting your fans to the connectors on the pump is that you can link the fan curve to the pump temp. Your fans won't ramp up and down as much, and can have a more progressive ramp rate. A Corsair Commander Pro would be needed for additional fans to be tied to the pump temp. Where do you currently have radiator mounted in your case?

Do you have any photos of the product label on the HX850 or a part number? We had a few different versions over the years, so I would need to know which one you have. The label will look similar to the one below:

Wow...wasn't expecting you to chop up your case, only pull the front panel off if it was removable to see what the difference in temps were. Good to hear you figured it all out and saw some good improvements.

Thanks for bringing this up, and sorry for the confusion. We're doing some maintenance on site right now, and it's possible something was changed on accident for the product linking. I notified our webteam and should be updated shortly.

This seems more like an airflow issue rather than the pump. You could try adding additional fans to the top and retest the radiator in the front and back. Based on the feedback @Semper gave, you could also try pulling the front fascia off with the current config and see how really restrict it is. If you see a significant drop, you have your culprit.

Wish I had the answer, but the last thing would be to give you a date and it not happen.

We will offer it in other regions/layouts, but I'm not sure when and which ones. While the previous K95 Platinum was offered world wide, the new XT uses PBT doubleshot keycaps which are a more involved process compared to ABS, and not as readily available. Best suggestion I can offer if you're looking for a keyboard right now, try and get your hands on one of the layouts above.

Good to hear you were able to purchase one through our site. CamLink 4k hasn't been discontinued, just high demand with the current situation. For reference to anyone else in your situation, but in a different region, the HD60 S+ would be a good alternative.

Sounds like the stabilizers might be worn after years of use. Since you're looking to switch to tactile feedback, want PBT key caps and a nice wrist rest, I'd suggest the K95 RGB Platinum XT. The new XT version comes with PBT keycaps and a cushion wrist rest. You also have the choice of Cherry MX Brown or Blue switches for tactile feedback. If you have any questions, let me know.

All comes down to preference, and does the keyboard offer what you want feature wise. First recommendation is to try them both in person, or at least something similar, at a local retailer. Not sure where you're located, but right now is a bit more difficult to do that for some regions. K63 comes with Cherry MX red switches, and just about every Corsair keyboard offers that switch type. Cherry MX Reds are linear, and will have the same actuation force all the way through; naturally feel more solid through the stroke. K55 will have membrane switches, which as best as I can describe, a soft progressive force, then drop actuation style. Let me know if you have questions about either of these.

If you're open to ambidextrous options, the Corsair M55 RGB Pro is a good solution. Let me know if you have any questions about it, and I can help you out.

Your cooler should be under warranty if it is defective (5-years). You can put in a support ticket, and one of our Technical Support agents can help with a replacement through the link below. Before we get that far though in writing off the cooler as failed, did moving the radiator to the front make a difference? Which RGB fans do you have installed? Is it only Overwatch that sees high temps? https://support.corsair.com/

It's possible there is a stock shortage in EU for the brown switch version. We currently only offer the K95 Platinum XT in a select few layouts: NA, UK, ND. I'm not sure which layout is typically used in Greece, but these are the part numbers to be on the look out for, possibly sourcing from a different region: NA Layout: CH-9127412-NA UK Layout: CH-9127412-UK ND Layout: CH-9127412-ND

Closest to your budget, I'd recommend the Corsair SP120 RGB pros (1 triple pack, 3 singles). Triple pack comes with a Lighting Node Core, which will give you RGB customization through the Corsair iCUE software. The Lighting Node Core only controls lighting, not fan speed, so you'll need to connect the fans to your motherboard or a separate fan controller like the Commander Pro.

No one on the team has any complaints about building in one. Cable management and controlling all the fans takes a lot more time, but that will be the situation with any cases in this class. The doors are hinged and removable, and we use a french door style drive cage to help hid all the wires. Which region are you in, and layout are you looking for?

With the H100X, you won't be able to set fan speed to water temp as this cooler isn't software controlled like some of our other models. Fan speeds will have to be controlled and linked through your motherboard or fan controller.

Finding someone who has built in both might be a little difficult. I'll be honest, I personally haven't build in 1000D, but other team members have. Please take no offense to this as I don't know your experience, but I would say if you are well experienced in building custom loops, 1000D is pretty straight forward. If you're more middle of the road and haven't done many loops, you might reconsider potentially both, as choosing parts and planning the loop is a huge hurdle before even getting started. If you do go forward with the 1000D build, I'd suggest checking out our Hydro X cooling configurator since it takes a lot of the guess work out: https://www.corsair.com/us/en/custom-cooling-configurator/

haha...no commission here, I'm not even in sales. Didn't check prices online before I posted, only threw out other options to keep an eye out for. Looks like everything below $100 is in short supply everywhere.

A Corsair 220T might work out for you depending on how short you're looking for. It's not going to be a short as a dual chamber design, but it does offer good airflow in a compact form factor.

Agreed, stock is limited in some regions right now. Other options that might come up available around the budget are TXM series. They are available in 550w to 850w.
