But just how much of an improvement can we expect from a repaste In this video Ill? Take you through the repasting process and show you the before and after temperatures, to see if its worth doing.. Just as a reminder, my Y530 has the quad core, i5 8300H CPU and Nvidia GTX 1060 graphics, which doesnt seem to be available in all regions in the US. For instance, I think you can only get the 1050 Ti. In order to see the difference. Ive tested at three different times., The first test was at stock settings with no changes apart from Windows updates. Since when I originally reviewed the machine in January.. After that, video went up, bob of all trades suggested a BIOS update that may help with thermals so Ive. Also gone from this version to the latest currently available, which sure enough in the change log notes that it updates the fan. Table. Lets start by establishing a baseline. All testing was completed with an ambient room temperature of 21 degrees Celsius.. These are the differences just with the BIOS update first to see if it changed, anything. Testing was done with a combined CPU and GPU workload by running the Aida64 stress test and heaven benchmark, at the same time to fully load the system. In terms of temperatures. I actually had slightly warmer with the new BIOS, with the 0.15v undervolt applied.. There was constant thermal throttling on the CPU at 94 degrees celsius at stock.

However, even with the undervolting, there was still intermittent thermal throttling when it would spike up, which I think is what were seeing with the warmer average after the update.. These are the clock speeds for the same tests just shown again. There wasnt really a difference here between the old or new bios, so it was good to rule that out now lets get into the repasting. Getting inside. The Y530 is quite straightforward: just use a phillips head screwdriver to remove the 11 screws underneath.. I then needed to use a pry tool to remove the bottom and access the internals. In the Y530. You dont actually need to remove the fans, but I wasnt sure going in so disconnected them first.. All you need to do is loosen 7 screws over the CPU and GPU dies and remove the heatpipes.. I had this piece of tape, sticking the fan to the heatpipes, which seemed difficult to remove. So I took the lazy approach of cutting it. Heres. What were looking at in terms of stock paste, underneath most of it seems to be on the removed heatsinks.. There are a fair few thermal pads here too. I didnt bother with replacing them like. I did in the Aero upgrade and just left them in place.. You can clean off the old paste using isopropyl alcohol Ive got an old kit of ArctiClean, which is just a paste remover and is by no means required, but thats. What I used.

Once cleaned up its time to apply the paste Im using Thermal Girzzly Kryonaut and, as always, please do feel free to tell me how Ive applied both too much and not enough paste at the same time.. I did make a bit of a mess, but it should get the job done. Once complete its basically a case of reversing the process, put the heatpipes back in place and screw them in.. I tried to do each screw around half way. First, before the final tightening to try and help spread the paste a bit more evenly., Stick the bottom panel back on and put the rest of the screws in and were done time to test it. Out. Ive expanded the results graph to include two new tests. After the repasting at stock settings and with the undervolt applied. At stock, there was no difference in terms of thermals. However, well see how performance was affected in the next graph. With the undervolt applied, though there is a 4 to 6 degree, improvement so were at least no longer hitting thermal throttling, which is an improvement Im happy with.. These are the clock speeds after the repasting, and we can see that even without the CPU undervolt, there is an improvement to CPU clock speed under this workload of more than 200MHz on average over all 4 cores., While its still thermal throttling here, as we just saw The throttling is less than before, and it is performing a bit better.

If we look at the result with the undervolt were getting the full 3.9GHz, all core turbo speed of the i5 8300H CPU, and while we could reach this before with the undervolting now the thermal Throttling has been eliminated. With a simple change of thermal paste. I was able to improve performance and lower temperatures in my Lenovo Y530 gaming laptop without any trouble.. It would be great if I could do this with more laptops, but unfortunately, I cant with borrowed review units as it would affect the results for other reviewers.. As I own the Y530, I can do whatever I like with it. Im sorry, this video took so long to make the last few months have been insanely busy Im actually putting off my first 9th gen laptop review to finally get this done. So I hope you found the results useful.. Let me know what sort of improvements youre getting from repasting and if youre new here get subscribed for future tech.
