Thank you all very much for your suggestions, I think I now understand the issues I am seeing. After my initial removal of the heatsink the second imprint was much better in my opinion: imprint2.jpg I believe I may have overtightened the Noctua mounting system, bottoming out the spring loaded screws...

Idle at 380 RPM@~45C. Load at 2000RPM, 85-95C 4100 MHz The case is open (no panels attached) but the GPU is close by. I just rested a 15cm fan against the GPU/CPU gap and it dropped the maximum temp to 79 so maybe I do have an airflow issue even in such a open enclosure. I'll try different cooler or...

Hi, Assuming HT is Hyper-Threading then it does not seem to make much of a difference: cpu_temp_2.png Just to be entirely clear the temp peaks are not random neither they are only at the start of a CPU load. The moment the load goes up the temp goes up. The moment the load goes down the temp goes do...

Dear SPCR forumites, I find myself in need of your wisdom once more. CPU: Intel i7-6700K Cooler: NOCTUA NH-D9L with two fans (front and mid) MB: ASUS Z170I PRO GAMING Open case (Ncase M1 with no panels) The behavior I am seeing is CPU temps exceeding 90°C on load. Even stranger is the temperature dy...

Right now its all assembled and living in its permanent home under my desk - I don't have plans to open it up again for a while. But if I do I'll give it a look. Too bad this discussion didn't get to this point 24 hours ago - I had it open twice yesterday evening to ghetto-mod access to the USB2 he...

I did notice on my Euler that the rear-left MB screwpost was a bit too low (rear-left with the MB upside-down and the IO-shield area being called front - or in other words, the post closest to the corner of the CPU). It was low by 1-2mm and I compensated by dropping in two of the paper-insulating w...

Actually you are entirely right Mike! I did not notice the the short threads - I admit I just assumed lookig on how bulged the CPU was. I am starting to think the I/O shield is the sole culprit. Check this out: http://regis.ic.cz/misc/case/shield.jpg I fitted the shield from the outside so it is rev...

Hmmmm.... So what you are saying is that the relative vertical position of the CPU heatblock vs the 4 mounting posts at the corners of the board are not correct, right? Ie, if the screw posts were a 1 or 2mm shorter, or the heatblock that much taller, this flex in the board would not happen? I wond...

Hi everyone, I think I have found rather nasty flaw in this case. When trying to figure out why my system behaves so strangely I have noticed massive deformation of the moteherboard inside the case: http://regis.ic.cz/misc/case/DSC02314.JPG About 2mm flex at roughly 2/3 of the board width. When look...

This is a dumb question but have you tried adding smoke to the airflow to see the difference in the pattern how the air itself is ejected from each fan? Nope, and we're not doing it! As far as I know this is only useable for laminar flow anyway. There is not much laminar flow downstream of a fan. :...

... but it reconfirms my experience that fan airflow and cooling don't have a very predictable relationship -- at least not at these fine detail levels. I would not be surprised a bit if higher FPM resulted in no decrease in temperature rise. But for it to result in actual increase... this seems re...

I think ISK is very good in terms of airflow and ventilation. That's why I choose it, among other things.
I agree with other points completely. It's just I am kind of "margin" guy. I always want to be safe.

If you forced all air to go through the vane, perhaps through a funnel of sorts, I imagine it would create artificial impedance. Yes it would. I think it shouldn't be a problem as the heatsing resistance is also arbitrary - depends on chosen heatsink. Only issue I can think of is this would create ...

Great article, thanks. Does anyone have any theory about why higher FPM can actually result in higher temperature rise (as seen for Noctua)? I really struggle to find any plausible explanation for that. Do you think the measured higher FPM can acutally mean lower total volume of air? This would requ...

@MikeC: As for the desktop users, unfortunately, they won’t be able to enjoy the benefits of Intel Switchable Graphics technology. Although Intel HD Graphics will now be present in all contemporary mainstream and low-end system, initialization of an external graphics accelerator during POST will c...

Thank you for the i5-661 power measurement Mike, I was unable to find this exact thing so I was using TDP for my calculations. However I can see the total consumption of the motherboard+i5-661 is 58.5W which is I believe more relevant number. At least some of it is powering the CPU if I read the art...

:lol: It is actually very simple. It has to fit in Antec ISK 300. http://www.silentpcreview.com/files/images/antec_isk300/isk300a.jpg I believe I actually first heard about this case here on SPCR. Of course now they are making the 150W version which might be just enough for i5+HD5570 I am planning. ...

10cm x 20 cm x 30 cm (~4"x8"x16") Core i5 or 7 PC is my application/project. Yes, there will be fans. It is the only affordable solution to cool this thing. I am more concerned about size. However somebody else may want fanless 220W PSU, I don' know. That is why I am asking. :) I am not trying to co...

MikeC: Yes, I agree with you it is not cost effective in terms of W/$. But Winmate PSU is extremely compact and absolutely silent. I think it depends on everyones priorities. I am not trying to pretend this is alternative to standard form PSU. It makes sense to buy this PSU only if you need the adva...

Dear SPCR forum members, some of you may know the 130W DC-DC ATX PSUs Mr. electrodacus is selling here: http://www.silentpcreview.com/forums/viewtopic.php?t=55353 I was looking for something bit more powerful and I found the same company producing the 130W PSUs is also making a 220W one: http://www....

Hello Mr. electrodacus, I would like to ask you if there is any chance you will be selling also the DD-2412AX or DD-WP12AX-220 220W DC-DC power supply form Winmate? (I cannot post liks yet but the PSUs can be found on Winmate web site) EDIT: Let me answer my own question by quotation: ... after this...
