Crazy-high Ryzen 3900X temperatures [solved]

[Topweasel]

Actually I've been shopping online for almost two decades. Just NEVER had anything taken out of my cart before. I mean I've never left anything in my cart for days or anything like that. But as I said, this was only a few hours... Such is life.

Any other time and it stays in there. Between low availability products and the holiday season this happens quiet a bit. It's funny but the best deals on Amazon have a clock in the cart for when they will be removed but anything else, maybe it stays in the cart but before checkout you will get a "item is no longer available".

For Tim I did 3 peas, one in the center and 1 over/very near the 2 core dies. It's been mentioned but its probably not smart to use the grain in the center approach on these CPU's the parts that get hot are the 2 core dies and a grain in the center might not spread all the way out to cover the dies.

The noctua paste I bought actually specifically mentioned that for bigger CPUs (specifically mentioning ryzen) one should apply 4 small dots in the corners and a bigger one in the middle. And that is what I did. With stock settings (except memory) I see temps around 73°C in cinebench (good old NH-D14). So that seems to work fine.

I will agree about memory clearance, but other than that big tower heatsink all the way.

Memory clearance isn't a big deal if you don't like RGB anyway. Hell the cheapest micron-e die kits (ballistix-sport) have a very small heat sink. I would say there is almost an inch of clearance.

Tower heatsinks also will last bascially as long as the company makes new mounting kits. The fans can be replaced. My NH-D14 was now probably 7-8 years old but still I could get a new AM4 kit for $15 (could have gotten it for free but then you need to first buy the CPU, send in a copy of the receipt and wait several weeks.). Anyway I will very likely keep this rig another 5+ years. I Highly doubt any AIO pump lasts that long. Note: Original fans still work on mine.

The bigger air coolers are monster sized and a pain in the ass to work around, especially if you haven't got rail thin arms and tiny hands.

Agree. That is the main downside of these coolers. If you tinker inside your rig very often, then an AIO is the better choice. Once the Tower is mounted it get's annoying to do anything without removing it. (EDIT: and don't put the case on the floor, that probably also a big part of staying dust free.)

And as a side note: Always get a case with dust filters or add them yourself. Used that rig for 7+ years and never cleaned the CPU heatsink. I did now for new build but there was barley any dust in there.

I found that out when I moved my Noctua NH-U14s from my main PC to my wife's computer.

I've used Intel CPU a long time prior to moving over to the 2700X, and the pea sized dob in the middle has always covered the heatspreader while the cooler is installed. When I removed the cooler from the 2700X, the same method only caused the paste to cover about 3/4 of the heatspreader.

When I went to put the new cooler back on it, I used a credit card to spread a very thin layer on the heatspreader (if you use too much, it will be pushed out of the sides of the cooler base).

The only time I've had to tinker in that area in all this time was replacing the rear exhaust fan because it'd gone. Trying to get a small pin connector in a tight spot without cutting myself up was difficult. Unfortunately, I don't know a set of plastic pliers made especially for this task. I've got hardwood floors, but I suspect it's still sucking up some dust which makes its way into the case and ruins my fans, even really high end, high quality ones like Noctuas. I've got filters though. I'll probably find or build a dolly system for my next case and have it sit a few inches off the ground.

AIO for me would only make sense if I were going with a very large radiator. Even then, they're not any more quiet than a good air cooler with good fans. The huge heatsinks out there are massive and take up a lot of space.
