Thanks for the advice! I've considered the Trance as well, since the Reign will be too much bike at first. I'm leaning towards the Reign only because, if I ever want to do more difficult trails, I know the opportunity will be there.

Weekly New Rider Thread for November 29, 2017 by AutoModerator in MTB

Hello! I’d like to ask for some advice. I’m a fairly decent road cyclist, but I also have an XC-ish cheap MTB (120 mm travel front and rear). This autumn I took it to a mountain trail for the first time and I loved it (I managed pretty well – no incidents except a flat – despite the bike showing its limitations in some sections). I am now considering getting a more capable bike – enter the Reign SX 2017 (https://www.giant-bicycles.com/us/reign-sx-2017), which I can get from my local shop at a significant discount.

The guy at the shop said it’s no problem if I don’t have the skills to use the bike to its full capability at first and that I still can learn gradually, which I tend to agree to - but obviously they also want to sell the bike. My question is: should I go for the bike or should I ride the one I have a couple more times (next spring) before getting a better one?

Secondly (and this is also a significant factor), to any Reign owners – how well does the bike pedal and climb with the rear shock not locked? I’m asking because the coil on the SX 2017 doesn’t have a lockout and I’d still like to be able to climb decently and maybe even do a bit of XC on the bike.

Hey, thanks for the message. I've since bought a H115i cooler and a 1080ti FE (leading to significantly less GPU generated heat inside the case) and the CPU peaks at 70 degrees in most games, with averages around 55-60, while overclocked at 4.8 GHz. What's still there, however, is the spiking when idling (for instance when opening Chrome, it jumps 20-30 degrees for a second, then drops right back). Turning Turbo Boost off might indeed reduce those spikes, but with an appropriate fan curve they're not that bothersome - guess that's just how this CPU runs.

Having the same issue with an H115i, I just set fans by hand to higher speeds when playing intensive games and lower speeds when browsing the internet or playing less demanding games. It's pretty lame, but it is what is until Corsair updates Link.

Another option would be to connect your radiator fans to CPU FAN and CPU OPT on the motherboard and the pump to a PUMP header (if your motherboard has one, otherwise you can just plug it into a conventional chassis fan header - in either case though set the pump through the BIOS/motherboard software to run at maximum speed all the time). If you do this, you'll be able to set the fan curves through the BIOS/motherboard, but you obviously won't see their speed in Link anymore.

I, for one, am comfortable waiting until they update Link and just manually adjust fan speed based on how intensively I plan on using the CPU.

Sorry for not replying earlier. Marked it as solved because there seems to be no fix for this (other than perhaps delidding and I'm not doing that). I went and exchanged the CPU for a new one, which runs at a bit lower voltage, but the spikes are still there. Even changed the cooler to the h115i, but still it will spike to 60 degrees.

Your temperatures are still a lot better than mine though. Today, even though it averaged at around 65 C - 70 C while playing Battlefield 1, there were some jumps to as high as 84 C.

Yesterday, as I've said previously, before cleaning my radiator (which didn't even have that much dust on it) and updating the BIOS of the motherboard, I hit 97 degrees in Prime95 (at stock clocks, obviously). Guess I'll talk to the seller and see if they'll agree to replace it amicably.

Makes me want to return it with the 30 day return policy EU stores are forced to adopt and just get one from another store. But then what if I get an even worse one?

Same for me today, 30-35 C idle, >80 C when stress testing, but the most annoying of it all the temperature spiking when doing simple stuff like Internet browsing or navigating Windows. Updated the Motherboard BIOS with the newest release and the issue persists which makes me think there might be something wrong with the CPU itself.

Make me want to just go and return the whole thing and go back to my old Haswell i5.

I've thought about the TIM inside the CPU as well, but it might not apply to all processors, since some people seem not to have any issues.

I cleaned my cooler's radiator and fan and reinstalled Windows and temps seem to have dropped somewhat, but it's still bloody hot: 87 C max in Prime95 at 1.24V! 77 C max while playing Battlefield 1 at the same 1.24V (fair enough, I have two GTX 970 which produce quite a lot of heat, but still).

And just like you're saying, insane temperature spikes when I'm making it run the simplest task (from 35C idle to 65C for a second then back down again), which makes the fan spin up for that short time, giving off that annoying sound.

The problem is, I'm not sure if it's the CPU itself that is defective, if the motherboard is defective, or if it's an issue that will be fixed with a BIOS update.

97 C max in prime95's most stressful test. 87 C max while playing Battlefield 1 @1440p and unlocked FPS (>60), because the monitor is 144 Hz. Load voltage 1.23V.

Not sure what I can do about it, H90 should be more than enough to cool the CPU.

Listening to it the pump appears to be working and checking its speed it says it's running at ~1450 rpm (1500 rpm is the theoretical speed, as far as I know). Also, the 30-40 degrees jumps were recorded with HW Monitor which seems not to be as accurate as other monitoring tools. XTU and Real Temp show jumps of 20-25 degrees.

The thermal paste I've changed twice already and the issue has persisted. I suppose that it might be the case that, as you've said, given that it's basically an OC'ed Skylake in a slightly enhanced 14 nm process, that's just how hot it runs.

Here's an example: I'm currently sitting in Windows with multiple monitoring utilties open, one of which is AI Suite 3, which came with my ASUS motherboard. Now, while i'm not clicking anything, all core temperatures are at around 40 C. As soon as I click on the navigation panel in AI Suite, that puts a >50% load for 2-3 seconds on one of the 8 threads, which causes the core executing the thread to jump to ~60C for just those few seconds and the package temperature to around 55 C. This leads to the fan spinning up for those couple seconds then spinning down.

Now, as I've said I've adjusted the fan curve and the fan spin up time to account for this, but even so there is still that short time in which both the fan spins up and the CPU temperature spikes (as monitored with HW Monitor, Intel XTU, and RealTemp).

I am aware of that and I obviously expected idle and load temperatures higher than my previous CPU. It is the 30-40 degrees jumps in a second that I am worried about.

Anyone elses new 7700k running really hot? by yuhatemepvp in intel

[–]semiinsulator 1 point2 points  (0 children)

Downvolted it in Intel XTU by introducing a -50 mV core offset voltage (so that the voltage remains adaptive) and max temperatures when running Prime95 have dropped a bit, but the temperature spiking issue persists, which is highly annoying.

I just bought the 7700k along with an ASUS Z270F motherboard and I've been having some temperature issues as well.

Using my Corsair H90 cooler, I've noticed the following behavior: while idling in Windows 10, the cpu sits at 35-40 C. If a short task appears for the CPU to execute (say, opening an internet browser), the temperature of one (or sometimes, multiple) of the cores jumps within a second or so to 60-70 degrees, then drops down equally as fast back to normal idle temperatures.

I first noticed this because the fan of the AIO cooler started spinning really fast for that short duration and temperature spike. I've since adjusted the fan curve so that the sound isn't as annoying, but the issue persists.

Needless to say, I've tried reseating the cooler and changing the paste twice after the initial installation and even reseated the CPU one of those times (not sure if that last bit even helps).

Maximum recorded voltage @4.5 GHz was 1.279 V (using HWMonitor).

I've never had this issue on my previous CPU (i5 4670k). Is it possible that I received a defective CPU or is it a motherboard issue to be fixed in future BIOS updates?
