Thank you for your renewed enquiry.
We are of course delighted that the AMD Ryzen 7 5700G is now available again, even if the current price is surprising at first glance.
Our prices can vary depending on the purchasing situation. We purchase items from different suppliers to ensure availability. The purchase prices differ, for example, due to smaller quantities or additional import costs. In such cases, our sales price is also adjusted accordingly, which is why such fluctuations can occur. We therefore work with daily prices. See here: digitec.ch/en/wiki/6028
We always try to offer a price that is as fair as possible, even if we are not always completely successful in doing so.
Unfortunately, we currently have no offer from a supplier for the Ryzen 7 5700G. We are therefore currently unable to say whether or when the item will be available again.
In principle, the pre-coating that is usually present on the heat sink is sufficient. However, if this has already been used, the residue should be removed with cleaning alcohol or benzine and a soft cloth and a new thermal compound applied thinly and evenly to the CPU. There are relatively wide options when it comes to pastes. The simplest and cheapest is a silicone thermal paste (white). A little better and just as easy to use is a thermal paste containing silver (dark silvery). There are even better heat conduction pastes, but no more. These are usually liquid metals, but they should be handled with great care. One drop in the wrong place and the mainboard is broken. Possibly even more. Arctic MX thermal pastes are recommended and inexpensive. Thermal Grizzly Kryonaut are sometimes the best and of course more expensive. Noctua thermal pastes are also recommendable, but too expensive in my opinion. At a similar price, I would rather take a Thermal Grizzly.
Unfortunately, we are currently unable to obtain the desired processor from a supplier. Should this change, we will be happy to consider adding it to our range.
Hy! It's a normal cpu like an intel. There also have integrated gpu. The igpu not gona make your system faster. Only you can choose wich you want to use. In BIOS. They not gona work together.
Most likely, "promo" means a promotion code or a bundle of Warframe. I strongly assume that the "Sister of Parvos riptide pack" is meant. The update came out at this time c.a., so it would make sense.
What is meant here is that you get in-game items worth about 30 USD.
There are no add-ons to buy for Warframe in the sense that it is completely free-to-play. We don't know exactly which items these are, but probably boosters and platinum, possibly even a Prime.
