the Toshiba occb x500 SSDs offer a quick and simple way to upgrade your PC's performance prioritizing storage endurance the MLC NAND flash 50 X 500 series is suitable for users seeking well balanced feed and features the VX 500 is backed by a five-year warranty and comes in a variety of storage capacity excellent what's up guys welcome back to Pauls hardware today's video is hopefully going to answer the question can a 65 watt TDP 8 core 16 thread rise in seven and 1,700 CPU be cooled with this family CPU cooler right here this is a no fancy our 95 c fanless cooler it's rated for CPUs up to 95 watts cost me 130 bucks on Amazon and it shipped to me directly from South Korea it is also absolutely huge so it's not going to fit in most cases and it's pretty much always going to block at least the top PCIe slot on your motherboard if not the top one to two slots so well it works let's get right into the test setup that I have prepared first off I'm going to be comparing this here 95 C's performance to a relatively comparable in price cooler the Corsa H 100 IV 2 which costs 110 dollars that's a 240 millimeter all-in-one liquid cooler so the trade off is going to be better cooling with that device versus you are going to get added sound from both the pump as well as the fans on there now both of these coolers ship with am 3 mounts the H 100 IV to of course will ship with the name format now but this one the TR 95 C only ships with an A and 3 and 3 mat it has not been updated so for that purpose I had to use one of these ASUS motherboards across there 6 hero is what I'm testing with because it includes both a m4 and an three mounting holes that pass through the back of the motherboard I did actually also have to scrounge up an AM 3 backplate to mount this cooler properly with other than that I'm using an asus strix 1080 TI graphics card g-scale flare x 2 by 8 gig ddr4 memory kit at 3200 at least for the initial testing Patriot Hellfire quarter an 80 gig nvme SSD Leanne Lee PCT 60 open-air test bench that you can see right here and the corsair HX 1000 a power supply now the other isin 7 1700 has a 65 watt TDP it is still an 8 core 16 thread CPU like the 1700 X and 1800 X the 1700 X and 1800 X run at higher frequencies so the TDP or thermal design power is rated at a higher wattage which is basically the amount of heat that the cooler needs to be able to absorb and dissipate 95 watts of those higher end ones 1700 only runs at 3.0 gigahertz base frequency 3.7 gigahertz turbo and in my testing was running at 3 point 2 gigahertz when it was under load across all cores it shouldn't get quite as hot as the 1700 X and 1800 X therefore you have a lower TDP at 65 watts now this cooler could theoretically be paired up with a 1700 X in it or 1800 X although didn't quite go that far my aim was to get something that was powerful but not quite pushing the limit as far as what temperature it was going to be running at 24/7 because my ultimate goal it split this cooler in my home theater PC my ultimate home theater PC that I've been building which is supposed to be able to not just do HTPC tasks but also video recording as well as playing video games at high resolutions 4k and doing VR now for my testing my ambient temperature was at about 80 degrees Fahrenheit at least that's what I had my air conditioner thermostat set to that's about 27 degrees Celsius and that did vary by a couple degrees but that's my best bet at keeping things somewhat scientific here now for the test I'm going to be running of course I did an idle test which is just a boot up let the system go through startup procedures wait about 15 minutes and then take my old temperatures then I did I 264 is my CPU stress test and that's not quite as intensive when it comes to the max temperature it will output when you compare it to something like prime95 but it is well beyond anything I will actually do with this system especially in an HT PC environment of course let that run for 15 minutes as well and then took the temperature reading then 3dmark fire strike just to give myself something would test a variety of different configurations it has a CPU centric test it has Gaming tests the scores for that test shouldn't change but I again took the max temperature reading during it and then GTA 5 I just did standard gameplay for 15 minutes to simulate me playing a game on this system and and how hot it would get so let's jump right into the testing the baseline was my again corsair h 100 IV - with the risin 7 1700 idle temperature was 32 degrees Celsius pretty standard for my ambience the i-264 cpu stress test only got the CPU up to 47 degrees Celsius a testament to the H 100 IV to cooling prowess 3dmark fire strike gave me a couple scores the CPU score aka the physics score was sixteen thousand five hundred nine six and the overall score was 6925 again pretty typical for a 1080i in this environment the max temperature while running 3dmark fire strike was 51 degrees Celsius so actually a little bit hotter than the CPU stress test with lightest six before I think this is a result of specific cores getting hotter because when it's not using all the course it will run a specific single course up to I saw three point seven five gigahertz when it comes to the max core frequency then I played GTA 5 for about 50 ms not only got the CPU up to 48 degrees Celsius now when I was running across all cores with that under full load it was running at 3.2 gigahertz across all cores and the max temperature probably would have increased a couple degrees if I had left that itis 64 stress test run a little bit longer I let it run about thirty five minutes which is quite enough to saturate a full-size during 40 mm 240 millimeter all in one liquid cooler but there it is again that was just kind of more at baseline for comparison next up I swapped out the H 100 ib2 and I installed the no fan CR + 95 C along with the cooler itself you get a mounting kit with hardware for AMD platforms up to am3+ and Intel platforms up to LGA 1150 which would also work the bail GA 1151 the documentation was pretty clear and concise and they did include an extra set of spacers specifically for am-3 mounts and then I actually also had to go and scrounge up the am-3 mounting kit from my 990 FX board that I got that a m3 map from as well but fortunately once those brackets are installed in the back and all the posts are installed on the top it's pretty easy just drop the cooler straight down on top of it the screws going through the tops they are spring-loaded to apply some pressure there and it all comes together pretty easily except for my clearance issues I had encountered two different clearance issues one was with the plastic shroud that's on the crosshair 6 here oh it conflicted with that so I had to remove it I might I might just shave off some of the plastic when it comes to implementing this with my home theater PC but for now this was able to get things up and running also the memory the g.skill flex kit was just a bit too tall conflicted with this soft it out for a corsair lpx kit which is lower profile this kid is only running at its own leaf rated for 3,000 speed though so I was running it at 29 33 with the timings that were installed there so bear in mind with these next sets of tests I was running slightly slower memory but with everything installed I was able to load up wait for things to cool down and idle temperature was only at 37 degrees Celsius just 5 degrees warmer than the idle load with the corsair h 100 IV - then I loaded up the I 264 CPU stress test that got things a little bit warmer but still not too terrible at all 77 to 78 degrees Celsius was the max temperature I saw there and in case you're wondering at stock settings at 1700 is running at about one point one seven seven volts under load across all of the CPU cores next up was 3dmark fire strike CPU score here was 16,000 793 overall score was 7077 so even though I was running a slightly slower memory and the cooler was making things around a little bit warmer when it comes to the CPU let's look at a higher score but it's just within the margin of variance for testing something like three mark multiple times anyway though the max temperature was 66 degrees Celsius so again a bit warmer than the H 100 IV - but still very reasonable especially if you compare it to something like a decent rate stock cooler or something like that finally GTA 5 gameplay for about 15 minutes again and only saw temperatures at about 65 degrees Celsius on the CPU perfectly adequate for typical gameplay experience now with the no fancy i-95 see I had an idea well first off I'm probably not going to be using the rising 7 1700 I'm going to be using a risin 5 1600 X but you should be able to under bolt these CPUs so that's what I did next when you run a CPU at a lower voltage than what it's set to you're basically nothing that can go wrong that's not the way I should phrase this it's basically a win-win scenario as long as you don't experience instability so just like with overclocking you got to test some stuff out you got to start to tweak the voltage and bring it down a little bit but just like with the overclocking you can eventually experience system instability I was able to dial in a negative CPU voltage offset of minus point zero eight seven five and that actually ended up in the CPU load voltage being around one point zero six eight volts which is pretty much what I told it to do I am focusing on the voltage here while all the cores are under load do note that if you are testing this yourself if you are only doing something that's going to use one or two cores that turbo boost will take effect with these rising processors and you can see quick voltage spikes in a one point four volts or above range but as long as when you have everything under load you're seeing those more nominal numbers in the one point one five to one point two range that's usually more like what you would expect anyway though I did run some quick test after envel under bolting the idle temperature dropped by just two degrees Celsius thirty five degrees was what it was at I to 64 CPU stress test sixty six C average during those tests and it peaked at 72 degrees Celsius and dropped back down so about five to ten degrees cooler than without that under voltage applied and then 3dmark fire strike did get a bit lower score but still not terrible when it comes to the variants that comes from test run to test run CPU score was sixteen thousand three hundred seventy seven overall score was six thousand eight hundred and seventy nine and my max temperature there was only sixty two degrees Celsius so all L I am pretty damn impressed with the CR ninety-five C's performance and I'm pretty damn impressed also with Rhydon you know it's not often talked about the efficiency of Rison but the fact that it's only a 95 watt CPU if you're looking at an 1800 X or 1700 X drops to 65 watts with the 1700 or anything below that so even in my worst case scenario testing which was stock settings at high 260 for stress test we only peaked at 78 degrees Celsius and that's still a good 15 degrees C or more from the seventeen hundreds thermal limit of 95 degrees Celsius you could even potentially overclock this CPU just a little bit although I didn't explore that because once you start adding voltage and adding frequency especially across all the cores temperatures start to ramp up pretty quickly so so I'm super happy with the potential for this system and an HTTP C and the gaming environment of course it did not come up come without its drawbacks compatibility when it comes to the socket you choose compatibility when it comes to PCI Express expansion slots I don't think I mentioned very specifically but not only was my top by one PCIe slot blocked but also the top or the second slot which is the full length by 16 slot that the graphics card usually goes in was also blocked so when I installed the Sirah 95 C I had to move the GPU down to the secondary SLI position for that but even though it's a by 8 connection it still been performing just fine and I didn't really see much performance degradation at least when it comes to my game testing the guys that is all for this video I really hope you've enjoyed it I certainly have had a good time over the past 24 hours or so given this a bit of a test and I think there's a lot of potential out there not just for this CPU cooler because this one's a little bit harder to find it's also a full copper version of the CPU cooler it's even more hard to find but I'd like to see more family CPU coolers available I feel like they kind of come and go pretty quickly and there's not a whole lot of them out there and available I digress though as J might say thanks again for watching this video guys hit the thumbs up button on your way out if you enjoyed it leave some comments in the comment section down below I have more work on arctic panther as well as hg pc as well as typical video content coming to you very soon and we'll see you guys in the next video
