Also, most 3770K hit a brick wall at 4.6 or 4.7, regardless of voltage, so this may very well be the CPUs limit within recommended voltage range, and it can do it at 1.3V.

It's those tiny intel CPUs that make it seem like a lot of heat, but it is just heat concentrated in a small area. More total heat needs more total cooling capacity. That is why I use the Thermalright Extreme and Silverstone HE01. They are overkill for intel but absolutely necessary for AMD. Others who try the D14, D15, Cryorig, and Phanteks just can't seem to match the clocks I get no matter what they do.

These are two short runs with exactly the same hardware at different voltages. At 1.3 volts a mere 212 would be sufficient.





I do agree that case air flow is very important to overall system cooling. When I'm gaming the CPU stays nice and cool but everything else heats up. Better case fans are a big help there.

Hi guys!

Need an advice from experts and veterans like you smile.gif. Have posted it in NH-D15 thread but people seem to be more active here so hence the post.

I have installed NH-D15 in my R5 and so far am very pleased with it. I have been running some stress test to test my overclocks on the CPU lately and have noticed that even though CPU is like 75C when I touch the fins on the cooler they are cold/cool (pretty much all the way down. Even when I check the air coming from my case its not that warm at all.

I'm running 5820K @4.5Ghz @1.28V and on 85% temps go up to 75C which is I guess pretty good, but the fact that the heatsinks and the fins are cool has me worried that I need to repaste. I previously had AIO 240mm radiator and that one got pretty hot and the air comming out of it was hot - but perhaps thats because the liquid went thorugh it?

So my question is - are the fins and the heatpipes supposed to get hot when CPU is this temperature? Should I try to repaste? - I think I did a pretty good job, but smile.gif

Thanks a bunch!

No the heat pipes do not get hot.
To explain,
The only place heat is entering pipe is over CPU area of pipe. This boiling (expansion) pushes the vapor toward ends of pipe where it condenses and pull move vapor toward end of pipe. This condenses liquid is drawn back to the CPU area by wicking on the insides of pipe where it again boils, etc. If the pipes were to be hot or even vary warm anywhere but near the CPU the heatpipe would not be working as it is intended. Even the pipe between bottom of fins and CPU block is wicking liquid back to directly over CPU and is not any hotter than near the ends of pipes.

Now that said, if the CPU to cooler seat with TIM is not done properly, the heat may not be leaving the CPU as it should. Many people use too much TIM. Link in my sig to "Ways to Better Cooling" has a post about amount of TIM to use. less it generally better .. like a dob about the size iof a large grain of rice. Just enough so when the CPU and cooler are pressed together it make a round print almost or just to the edges of CPU. Click the link below and then the link to post #15.

Thanks this helps a lot! I guess I was used to different thing from the AIO I had - but this makes sense. As you said, I too have a habit of putting too much TIM on - did a better job second time around, but will probably repaste in the future and do it properly.

I would like to see more data to back this up (this is the first or second result on Google for comparing heatsinks). Currently running an 8370@4.6Ghz on 1.3375 volts (just a tad up from stock which is 1.3320) on an NH-D14, because nothing other than the Dark Rock Pro compared to it and watercooling. it seems that either cooler is only a 2-5C difference to the D14, and a lot of reviews pin it with a 6-core Intel build (which the die is bigger). Reviews either have the coolers at the top (by hairline degree differences) or slightly below - this does not make a guy want to go and run to buy a new cooler. One review noted that the Thermalright suffers poor contact from a bending bracket.

Edited for clarity. And because I'm wrong!

Could you supply a link to the review saying Thermalright has bending bracket? Sounds like it's totally bogus to me, and I've mounted and used a boatload of Thermalright coolers over the year, so would like to see how they came up with that kind of statement. Maybe they looked at the print and saw good contact in middle and not all the way around. Thing is the Thermalright base is convex, slightly more so front to back than side to side. This give it much better contact on concave IHSs while also being able to give great contact over the die on flat IHSs.

There's no escaping this screwup on my part sorry!!.. wrong tab, wrong heatsink (to be fair though, nobody sells the Ultra since 2010, at least in my country).
http://www.silentpcreview.com/article1367-page3.html this is the tab I had opened (HR-22) Didn't the Ultra use AMD's clip-on tabs (or am I thinking another heatsink)?

Hopefully someone can test a d14 vs d15 with both having 140mm push/pull set ups since they seem pretty close.

Thanks.
Nothing for you to be apologizing for. The reviewer is to blame, not you.

Yeah, Ultra has been out of production a long time now, but is still a very good cooler. Last I knew updated mount is still available, but hard to find. The old coolers have a thicker base than most of the new ones, All that have the thick base use the same mount as Ultra uses. wink.gif

Sadly the reviewer doesn't know what they are talking about . They remove the plastic washer for barrel studs which means top mount backet is lower / closer to motherboard / cpu on front side, then mount cooler with crossbar and tighten the tension / pressure bolt in middle of cooler until it gaps slightly one front and back of base. This tension bolt pushs directly in the middle of cooler base, meaning even pressure is created over entire base, meaning if offset of cooler was creating more weight on back of cooler it would show in the TIM print. But the 2nd TIM print has best contact dead center on the CPU. Also the tension bolt is for up to about 100psf, so of course it can case the crossbar to spring up a little when tightened. The metal is not bending, it is flexing. A bend is permanent. A flex returns to original shape. tongue.gif

I use those coolers because they come with the most powerful fans. With similar fans to the others they would perform about the same as the others I believe. I see a direct correlation between fan speed and CPU temperatures. Also case air flow makes a big difference.

You have a great 8370! I don't have a 4.6 run recorded but mine needs 1.476 vcore for 4.7. Then it runs fine at 5 ghz @ 1.5 vcore. Then I got a 2nd 8370 and it's a piggy needing 1.548 vcore for 5 ghz.

The Thermalright AMD mount isn't that good but is good enough. I don't really trust it and in fact damaged a motherboard working with it. The HE01 AMD mount is much simpler and stronger.
