AABCOOLING RAM Heatsink 4 - a set of 8 Copper Heatsinks for RAM and GPU memory, Chip, Mosfet, Conductive Adhesive Tape on back, Cooler GPU Chips VRAM

These heatsinks were sort of OK. In this instance it seems that even ram heatsinks are in short supply and that being gpu ram. These could have been a bit wider so I had to use two per ram chip. They are fine now until I get correctly sized heatsinks

These are excellent, after my first purchase I thought they were a little small however that is great as you can apply tgem directly to components, etc.I benchmarked my ram before many times using Novabench, when compiling the data there is a small however very noticeable difference between the RAM with and without these heatsinks.I have gone a step further and I have now decided to get some aluminium to use on top of the copper heatsink as copper is a better thermal conductor than aluminium, it likes to suck up and give it's heat away easily, wheareas aluminium likes to suck heat yet retains that heat for longer than copper, that's why in one area aluminium heatsinks are thinner to allow for a fan to assist in helping the metal release it's heat.So to be clear, I believe these should be used first, then have an aluminium heatsink on top with a fan to draw out any more heat, this I have found is an excellent way to improve the performance of the RAM as well as other components on your motherboard!!Don't go cheap on fans however and be sure to use static pressure fans when you need to "push" air through a radiator or similar, case fans just tend to be more airflow without the power of a static pressure fan.Hope this review helps, these heatsinks have most definetly helped me!!The Reviewer

very easy to install and for me the adhesions are very good. I've put this on the backplate of my GPU which 90 degree to the ground (so the adhesives could not be really tested in my situation, but as I get the feeling of them, they are feel strong).in regards of the performance, I see 4-7 degree (c) cooling deference (by attaching all 8 heatsinks).

Had to buy two packets as my gpu is 12g but the heatsink's perform very well the adhesive pads are terrible though I reccomend not even attempting to use them after what seemed ages of trying to peel the film of them I just gave up and ordered some thermal glue as they dont seem like that are suited for its purpose. I have a known hot card the msi gtx 1080ti and these paired with a accelero 4 brought my temp's from going into the 90's to having the max its hit in a week 59 degrees this was in the mil sim game SQUAD with all setting on ultra .... these little heatsink's are a worth while purchase I feel

Would not count on these staying on the ram , unless there is no danger in your setup if they detach and fall on something else I would not use them. On my RTX2080 with H55 and cracken G12 i had 0 issues with no heat sinks and because I've noticed the tape they come is not very convincing and using a phanteks shift X case I decided not to risk it.

Edit: after some time the great from the component it was stuck to loosened the glue and they all fell off. Wouldn't suggest using in a position when gravity could slide then off over thingThey look good and I've not had any overheating issues so I can only assume they're doing their job! The sticky was nice and strong and were packaged well.

Heatsink is fine hut adhesive is useless. If you plan to paste them, you need to buy other thermal adeshive.

Good size and the adhesive tape is fairly good. On smaller VRMs I used Alaska thermal tape as these came off under their own weight compared to area. On the GPUs ram they have stayed on. Good value over all.
