UPDATE #3 @ 01-10-2017: Replaced my EVGA GTX 1050 Ti SC with an MSI GTX 1060 AERO ITX 3GB. Fits perfectly. GPU temps peak at 67C-70C depending on ambient, which has to be a testament to the design of the AERO ITX card - I'm impressed
UPDATE #2 @ 03-07-2017: Added RGB strip from Phanteks + side panel, made of acryllic, with 3mm perforation.
UPDATE #1 @ 31-05-2017: modded the PSU mount so that it is 15mm scooted towards the side panel. That makes space for a Big Shuriken 2 Rev. B., which keeps the i7-7700k a lot cooler than the C7 does.
Original build description @ 31-03-2017:
- Silent and efficient (need it on my desk)
- Easy maintenance (positive pressure required)
- Powerful database handling (that's where the "overkill" CPU comes in)
- Easy to transport
- Must provide >144hz framerates in DOTA2 and CSGO
- Expansion options for storage
- C7 backplate was conflicting with a few chips on the back on the Z270i, so I had to ghetto mod the backplate with a swiss army knife.
- The TU100B is a thermal nightmare, so I modded it with 2x A9x14's in the bottom of the case, replaced the front intake fan with a ML120 Pro White, flipped the PSU (the SF600 never spins anyway with my low wattage system, so there's no counter-acting fan direction, and flipping the PSU moves the hot parts of it away from the CPU), undervolted my i7-7700K TO 1.07V vcore, enabled max cstates and speedstep, and disabled turbo. 4.2ghz @ 33-35C idle, 76-79C stress testing, and 70-75C in heavy workloads/gaming.
- (See update #1) After having spent a lot of time calibrating the C7 as stated above, I realized that the main limitation of my system was my poor cooling solution. The solution was modding the case to allow installation of a Big Shuriken 2 Rev. B. It is significantly better than the C7: I now run stock CPU clock speeds with turbo on and RAM set to 3000 Mhz (wanted to do the XMP but after every hard off-switch, the system fails to post if I use XMP) and hitting 75C averages in OCCT testing. So there's even room for a little overclock if I wanted to, but it dips into the 80's so I'm perfectly happy as it is.
Very quiet profile now, nice low temps and speedstep/cstates work just lovely when idle.
Big shoutout to simmons (OCN), fer (OCN), Myrdahl (OCN) and really everone else at OCN who contributed to the thread. Also big shoutout to reddit user /u/stupidasian94 and PCPP user alixzibit
Lovely chip. When undervolted to 1.07V vcore @ 4.2ghz (all cstates enabled, speedstep enabled and turbo off), this thing is cool enough for the C7 to take it easy RPM-wise. The system is 33-35C on idle with CPU fan set to 38%, which is nearly inaudible. I'm sure if I build a new system with a beefier cooler and better airflow, this thing will hit a nice overclock. I have faith in my silicon :)
Upgraded to the Big Shuriken 2 rev. b. after having used the Cryorig C7 in my TU100B. Went from having to disable turbo boost in order to stay under 80C in OCCT to now having boost enabled as well as RAM overclocked and hitting averages of 75C with momentary spikes into the low 80s. I couldn't be happier. Did require some modding of the case, but that's hardly a fault of the CPU cooler :). Tried "upgrading" the stock fan with he Noctua A12x15, but surprisingly the Noctua fans had worse thermal performance in this use-case than the stock Scythe fan, and acoustically there was a negligible difference between the two. Scythe really made a great product here, imo.
Does the job just fine, no more no less. I'm very happy about how the fan performs at <40% fan speeds, but above that it starts to get very noticable. To get 5 stars, Cryorig should've provided a non-proprietary fan, so mounting an alternative fan would be easy. I would prefer a A9x14 fan for this cooler. It's doable - you just have to mount it with zip-ties. But it's not a 5-star product if it REQUIRES modding to fulfill my wishes. Also, the backplate has conflicts with the ASUS Z270i motherboard, but I'm pretty sure that's the motherboard's fault.
EDIT: now replaced the C7 with the Big Shuriken 2 Rev. B. in my TU100B
This stuff is rock solid. Litterally. This paste was so dense, I'm surprised they managed to keep it liquid.
Great features, but a bit too much heatsink going on, in my opinion. Finding coolers that fit this motherboard is a pain, but if you stick to Noctua or companies that stay within the no-fly zone of the CPU, you'll be fine. The BIOS has great features too. For 5 stars, I would've liked to see 1) the chips on the bottom of the mobo to not conflict with CPU cooler backplate, as this requires modding, and 2) an additional fan header and/or 3) at least the option to PWM control the AIO_PUMP. I don't for the love of my life understand why there is no option to enable QFAN control of the AIO_PUMP header, so we can control the pressurization of our system without compromising sound profile (i.e. have intake fans on one header and exhausts on another), but whatever. Just beware: If you plug in fans on the AIO_PUMP header, it WILL run, but it will ONLY run at 100% speed. That's unbearably loud to me. You might be able to find a LNA or something along those lines, but I haven't tried any such route. I just y-split 2 times for my 3 case fans on the SYS_FAN header.
EDIT: I actually found the AIO_PUMP Q-Fan enabler in the Bios under "Advanced" --> "Monitor" --> "QFan control" --> "AIO_PUMP control" --> change from "Disabled" to "PWM". Hadn't thought of looking under monitoring settings, my bad I guess. Changing the AIO_PUMP to PWM-enabled caused my system not to POST because CPU_FAN all of a sudden wasn't recognized, but I'll fiddle around with it and revert the review back to 4 stars if the problem persists after fiddling with it.
EDIT2: So after fiddling around, the following worked out for me and got the system POST'ing: disable AIO_PUMP PWM --> reboot --> ENABLE AIO_PUMP PWM --> recalibrate fans using Q-Fan recalibration --> reboot --> disable AIO_PUMP PWM --> reboot --> enable AIO_PUMP PWM --> reboot. I guess it's some minor bug.
EDIT3: So, after having fiddled around a bit with using the XMP of my Corsair 16gb 3200 mhz DDR kit with 16-18-18-36 @ 1.35V, I've come to the conclusion that this motherboard simply can't run the OC'ed ram properly at their rated settings. The issue isn't stability or performance - in those aspects, the mobo handles the XMP well. The issue is that after every hard off-state (ie. turning off the power supply/wall switch), the system won't POST for 2-3 boots. On the 3rd boot, it resets the RAM speed to 2133mhz (or the default frequency of the RAM) and boots correctly. I've error-tested it and found that the issue is related to the voltage of the XMP. If I run the ram at a higher voltage, it is stable even after hard resets. I'm currently running it at 1.45V and experiencing no issues, either stability-wise or POST-wise, regardless of whether it's a hard or soft off-switch
EDIT4: With BIOS version 0808, which I installed on the 2nd of July, 2017, ASUS finally managed to fix the cold-booting error with RAM speeds >2400mhz. No more manual tweaking of RAM voltage, CPU System Agent and VCCIO. Thanks, ASUS, but seriously... why that long?
EDIT5: Having just looked over at all this **** I've been through with this board, I'm not actually sure I think this is a 4-star board. It might be worth 4 stars today with the latest BIOS, but considering the state it shipped it, it has been a 3-star experience at best for me. Too many stupid bugs and weird **** from ASUS .
No faults, does what it says on the box.
EDIT: I have confirmed with a seperate DDR4-kit that the post-hard-off-switch boot/POST-issue mentioned in my ASUS Z270i part review is NOT related to the RAM-kit but rather the mobo not being able to run the XMP profile at it's rated voltage.
Great value for money SATA SSD. Later on, I will be adding m.2 drives and clone the system from the SADA SSD to the M.2, or alternatively just reset my system on the M.2, but for now, this is a very good budget alternative. Plenty of space for a reasonable postgresql database and my two favourite games: CSGO and DOTA2.
Absolutely astonished about this cards thermal performance in my TU100B. Basically hits the same or ever-so-slightly lower max temps comparet to the EVGA GTX 1050 TI SC it has replaced. Heaven loops maxes at 67C-70C depending on ambient temps, and gaming is pretty much the same. My only gripe with the card is the coil whine, but that's random AFAIK and I won't hold that against the product design. An extended burn-in test reduced the coil whine noticeably, but it's still there.
As I said previously for my CPU cooler, any product that requires modding to do something that is WELL within the scopes of reasonable use can't get 5 stars from me. And oh boy, does the TU100 need modding to perform REASONABLY well with midrange components. I modded the bottom of the case for mounting of 2x Noctua A9x14's for air intake. Further mods might be required: a 92-120mm case fan on the side panel as well as 2x 80mm exhaust fans on the top between the handle will help with providing the airflow this case so desperately needs and DOESN'T have from stock. I wouldn't get this case if I wasn't ready to make these mods.
That being said, I am in love with this case. I'm sure normal people would rate it at 2-3 stars MAX, but I just can't do that. I want to give it 5 so badly, but I know that's just me being super biased. So 4 it is, and that's kind of generous, I feel like.
Big shoutout to the OCN community of TU100 owners - fer, simmons, myrdahl, and all the others from the thread - and reddit user /u/stupidasian94. Lots of help from other TU100 owners made it possible for me to do this build despite the difficulties entailed.
List of mods made:
Cut 2 holes in the bottom of the case with a hole saw and drilled 8 4mm holes for mounting of 2 Noctua A9x14's. Alterantively, one can go for a 120mm A12x15 or similar low-height 120mm fan and/or perforate the bottom panel instead of cutting holes for the fans.
Drilled 4 holes in the back panel for scooting the PSU roughly 15mm towards the side panel. This enables the CPU coolers of up to 70-75mm's to be mounted. Keep in mind you need at least 1cm of clearance between the CPU fan and the PSU in order for there to be sufficient air available to the fan of the CPU cooler. After having scooted the PSU, I've stuffed the hole with a ~20mm wide piece of perforated acryllic. Long-term plan is to replace this with a piece of perforated aluminium, spray-painted black.
Replaced the case feet with rubber feet. A fairly simple mod that drastically improves quality-of-life for users of the TU100. The stock case feet scratch any surface they go on, so you either have to put some sort of anti-scratch tape on them or replace them. Also, the stock case feet at <5mm high, and when the bottom panel is modded for air intakes, the fans really need some added height to have sufficient body of air available. Otherwise, you get turbulence and/or reduced cooling efficiency.
This is amazing. Quite simply amazing. I don't think it has ever spun outside of the few seconds during powering on.
Specifically for use in the TU100: Because it never spins, I can flip it in my case, so that the hottest part of the PSU is moved away from the CPU socket. This saves a few degrees in temps, but if you have system wattage high enough that it needs the fan to spin, I wouldn't flip the PSU as the fan of the PSU will fight the CPU cooler for the same air, effectively making both of them less efficient.
Silent, efficient, easy to install, comes PACKED with accessories (Y-splitter, extension cable, LNA, rubber mounts and screws). Would give it 6 stars if I could.
Absolutely wonderful case fan. A bit too noisy on 80%+, but that's to be expected. Moves a ton of air on low/mid RPMs and the LED is lovely and fairly understated in the TU100.
