this video be pretty easy compared to the rest we're just doing an a/b comparison of cold plate size as it applies to thread Ripper and thermal testing on thread refer using two Noctua n hu 14s coolers one of which is a TR for addition with the full-coverage cold plate and the other one has an LGA 11 5 X cold plate all were looking at is cold plate size impact on thermal performance before getting to that this video is brought to you by synergy the software that lets you share a keyboard and mouse between multiple systems if you have limited desk space and multiple computers to command that synergy removes the need for separate peripherals or a KVM and works as over the network software use our link below to get 50% off the basic or pro version this testing took some modding these are both air coolers and they're also the only coolers we presently have where it's the same cooler at the heart of it with only one difference being the cold blade so we do a proper AV comparison so the LGA 1150 xcolor the much smaller cold plate size only really contacts the middle it doesn't even contact all of the dies all the way across this is worse than the closed loop liquid cooler coverage which at least those cover the entire die exposure area if not the entire i HS so you at least get heat away from the dies on those but with this one because it's not built for thread ripper it obviously doesn't cover the whole thing probably covers about the middle to bottom corner of each of the four modules two of which are active and that's it so it's going to be hotter but we are serious we want to see what the impact was the full plate so basically we took the mounting hardware for this one the spreader pro on which is pretty clear by that and took that off of there moved it over here drilled some holes so that the mounting hardware would support screws going through into the the cold plate of this one the LGA one and we're able to get some screws today to hold it in place also added rubber dampers here to provide opposition as it's being mounted and make sure that there's enough mounting force and once it's all said and done and the coolers tightened down it doesn't move at all it's got the same mounting pressure as this thing does because using the same mounting kit and there's a rubber bumper there that means that we're actually applying downward force where it needs to be applied everything's good the only thing that's not good is the cold blade size so that's what we're testing we're looking at these results with a it's Navy comparison the same heatpipes same thin stack everything the heat pipes are the same distance apart that's one note about this cooler is because they basically took an existing design and added a bigger cold plate to it you're looking at a situation where it could certainly be optimized more but to do that in time for launch was probably not feasible and might have cost too much for the volume they're expecting to sell so Noctua has a heat pipe design that's basically identical to this one where the heat pipes don't fully contact the entire cold plate of this unit so it's not optimal but it might still be good enough we're not really here to review the cooler today we are here to look at the cold plate difference but that does help control our variables of it so we've even got the same heat pipe layout as this one that's pretty interesting and it's not contacting the entire cold plate so it's not going to transfer as well so hence the question of does it still do better with just that cold plate change for testing we're doing two prime95 was way too abusive on the LGA 1150 x cooler it was throttling like crazy so we just didn't know what temperature would actually be hitting the CPU that is with prime running it was too much for this candle and so you look at a difference where you're hitting the thermal cap and one not the other it's not really realistic difference so we threw out prime for this we end up using handbrake and blender because those were less intensive than prime still intensive in real workloads handbrake ended up being a bit better for the Swan blender was still kind of getting into throttled territory but handbrake was pretty free and clear of that and that's what we're testing the clock rate and voltages were both fixed they were set manually so there's no turbo boosting there's no change of the voltage or anything like that and we'll have those numbers specifically in the article link of the description below if you'd like to see those numbers so let's get on with results these charts are pretty simple with handbrake transcoding one of our videos for 30 minutes the CPU reaches steady state and produces a temperature delta of eleven saltiest between to the tr4 cold blade is heavily advantaged in this particular task keeping to around 57 Celsius versus the nearly throttling LGA 1150 xq ler threader per throttle that 68 C T die or 95 c TC TL t control the idle Delta is 2.8 Celsius favoring the TR for cold blade moving on to blender our load delta is about 10.5 Celsius once again producing a favorable results for the TR for cooler might be a bigger temperature difference here than we can see because we were starting to clock throttle on the LGA 1150 unit they could all be different but interesting because channel design could impact the efficiency of a solution for example a full-coverage liquid block here if you pull an older design the channeling is going to be optimized for a die in the center of the IHS one die liquid flows over that die through some gaskets and out the other way whereas with this setup because you've got two sets of active dies in opposing corners a more optimized channel layout may be beneficial now once you're under liquid does it really matter probably not a lot for most users because again once you're already under liquid like with the X 62 it's just kind of difficult to make the thing heat up enough to be relevant even with overclocking it really temperature was not a concern with Red River but there's still room to optimize all these things those rooms optimize this because again the heat pipes could come out some more get some better spread over the cold plate and the rest of the cooler but it shuts the question up doesn't do well enough as is so this is one a review of this thing of the Nhu 14s I think it's called yes TR for addition not a review that we're not doing comparative data versus other coolers all we're doing is what's the cold blade difference so the next thing to look at would probably be added a cold plate TLC design for the you're looking at the kind of mid coverage ace attack design versus the Apollo tech one coming out from animatics we've got a full cold plate but is the pump actually covering that entire area is there actually are there liquid channels through that entire area or is just a white or a copper footprint so what we looking at that eventually just whenever they come in I don't have them that's all for this one as always you go to patreon.com/scishow and accident helps out directly you find these types of tests av-test
