Question about 970 fan RPM

I just got a 970 and so far I'm loving the performance, but I noticed something a little weird about how it controls the fans. My temps hover right around 60 when gaming, so I'm just at the threshold of where the fans kick in. When I look at the fan RPM graph in afterburner they are switching rapidly between 600 RPM and 0 RPM. I was wondering if this is harmful to the fans in any way, because from what I can see in afterburner the card is constantly turning the fans on and off. I'll post a pic below of what I'm talking about.

maybe overclock your card, let it reach a bit higher temperature, so the fans could remained spinning?

  • Question about T400s fan

    Hi, I have a question for T400s owners,
    Have any of you noticed a "hiccup" in the t400s fan?  I can hear the fan (its not a quiet as some people say it is) and it clicks or hiccups kind of in a rhythmic pace every few seconds. I'm wondering if the fan is going bad

    Hello Samtoossi,
    I have the exact same phenomenon on my brand new T400s (2808/D9G). It sound like there is some sort of strange mechanism to "respin up" the fan every few seconds : the fan speed is not constant at any time in fact, it spins a little down, then there is a little boost, and again and again.
    I'm not sure this is an issue, even if I wondered at first... And now knowing I'm not alone...
    Did you contact Lenovo for that ?
    Thanls
    No,  I just use TPFanControl to keep the fan off most of the time. I'll wait until something major happens and then include this issue into the mix when I call lenovo. Im kind of hesitant to get anything in this laptop replaced right now. If its the fan that needs to replaced, its not a big deal, but If its a motherboard issue there is no way in I'm going to replace it because there are many reports by other owners of annoying processor whine, unresolved random shutdowns, and melted speakers. I'm pretty happy with the current state of my laptop, thanks to TPFanControl
    FYI, this looks very similar to the infamous "pulsing fan" problem that affected many of the earlier IBM Thinkpads. Its due to ACPI polling the fan RPM every few seconds (every 6 sec for my T400s). IBM eventually released a BIOS update which fixed the problem. If you run TPFanControl, you will see that the pulsing is only noticeable under fan speed 2 which constantly changes speed. Fan speeds 1, 3,4,5,6,7 don't have this problem (speed 3 kind of has it, but its no where as annoying). It could be that this is a common problem, but most people just don't hear it because of ambient noise or they're just not bothered by it. Hopefully, a BIOS update in the future fixes this problem.
    If you decide to call Lenovo and have the fan replaced, let me know how it works out

  • Question about youview fan

    Hi guys
    I just bought a bt youview box and started using it and noticed that it was getting hot. The box wasn't making any noise really so I looked at the back and noticed the fan wasn't running. So I took it back to the shop a d they gave me a new one get home turn it on and the fan isn't running ? Does the fan only cut in when the box gets really hot ? Or I'm I just really unlucky.
    I heard these youview boxes can be noisy but I can't hear anything apart from the hard drive ticking abit.
    Any help please

  • Much better- and question about constant fan noise

    i couldn't start anew thread a few minutes ago. I replied to 2 threads, then the startanew thread iconmagically appeard! I am not making it up.
    any way- i posted a while back about noise. I thought it may be the hard drive. But definatley it sounds like the fan(s) in my MBP dual core
    my MPB was silen when i first bough it. then a few month in it got noisy. Now thw fans are on all the time.
    anyone else with a MPB that is just noisy? this *****! macs are almost always quiet. this is annoying acually. and it is non stop! i can't recal a moment when the fns were not winding like tiny air craft jet engines! LOL wel, it's not that funy actually.
    the noise does change in pitch on occasion. sort of like they slow down a tiny bit. other wise they just hum away.
    I had a G-4 I mac- SILENT! then a dual G-5 tower- it was quest until it roared up on a task, then it roared with power then got quiet again.
    but this tiny mpbis just noisy!
    Well, i hoope it is the fans, not the HD. It prettty much sounds like fans, and constant.
    but considering theroom temp is abou 68 in here, whywould the fans be on? and non stop?
    we live in a cold climate, so it's not a 100 weather.
    any help with the fans and perhaps a test or a way to turn them down? does my system think the core is hot?
    thanks for any help

    only about 13% is a peak ap. nothing major, nor a lot of stuff. but nothing consuming 30 40 or more percent or anything. Nothing running except safar in this case, activity monitor.nothingexcessive like 10 aps , whihc i have done in the past as we know the macs can handle it
    well, nothing seems out of the ordinary.
    I included a pic from that FAN CONTROL AP- well was going to, but not sure how.
    any way my stats from it are:
    base speed, 1500 rpm (on both actually)
    ower threshhold 122F
    upper 176F
    current temp at that moment was 101F
    can someone compare their fans to mine and their temp- i assume it is the cpu core temp.
    any way, not sure what is a safe range, nor why my fans are running non-stop.
    just noisy? but like i said they do occilate a little ans slow and the hum gets deeper then they go back to normal which is a slightly higher pitch.
    as for that iStat pro ap. i opened it and it just made my application dock bar flash then the dock came back. The Istat pro didn't open.
    Um- it looks like a widget. I may have taken my widget ap of some time ago. I hve yahoo widgets on. but not sure how to get that istat to work. I can't even recall the name of the apple widget program.
    thanksfor help on tracking this noise down-
    are any of your guys's fans really noisy? is this common? mine is just non-stop but if my settings are off or if there is areason, then I can adjust it from there. just want to know what the "normal range" or operation of the fans are. but man they are noisy for a mbp. and they WERE QUIET when i first got this laptop.
    thanks again

  • IBook 12" 1.33 Question about the Fan?

    I am looking to purchase an apple laptop for class and work. I have a HP laptop now that runs great and is fine, except the underlying problem is windows just plain ***** and I'm tired of all the crap that goes wrong with windows. I have a mac desktop, the new iMac 20" core duo, but am looking to replace this laptop since I may need it for school and work.
    My question is geared towards those that use their iBook with light/moderate use...does the fan run constantly and is it loud? I think the most annoying thing about this HP laptop is sitting in class or a meeting and the fan is running and its LOUD! So, if I were typically using microsoft office (i.e. word, excel) or photoshop, would the fan be running a lot?? Thanks for any advice!

    Have to politely disagree with this comment... an iBook's fan can be quite loud! It's quite obvious when it's on vs. when it's off!!
    And it could run while using Office depending upon
    a) air circulation issues
    b) background indexing
    c) hard drive room
    etc.
    But having said all that, I don't think this should prevent you from buying an iBook as the fan will rarely come on under normal operating circumstances.
    Until recently, after upgrading to the laste OS and security update, and seemingly ONLY when indexing an external hard drive, our iBooks' fans have practically never come on at all.

  • Quick question about Panaflo fan

    Will the Neo2 throttle this fan's speed based on temperature readings like it does with the stock HSF? I'd prefer it to run max speed most of the time.

    Smart CPU Fan target is what I guess you're referring to? It's not on... but when I look at the RPMs the fan seems to cycle between speeds of 3375 and 4000RPM... it's usually consistent with temperature increases.
    But if that's not the case then please educate me, the fan sensor could be going nuts, I don't know...

  • Questions about controlling fans.. using programs like smcFan Controll

    I am in Brazil and the high of the day is like in the 80's so my temps on my MacBook Pro jump to 150 F, I was wondering if I should use a program to increase my fan speed. For some reason even if the temps jump to 150 (F) my Mac doesn't up my fan speed. Is that normal? Should I use some program, such as smcFan Control to up my RPM's on the fans?
    Thanks for the responses!

    Yes, from anecdotal reports here that seems to be true, but it's not much sooner — just a little.
    But it isn't the operating system that makes the difference; it's that the hardware itself is tuned a little differently. From the fact that your machine was able to run OS X 10.5.8, I was able to tell that it wasn't one of the newer machines. It may be that the threshold of danger from overheating with the i5 and i7 processors is a bit lower than the 105°C/221°F for your Core 2 Duo; I don't know for sure.

  • Question About Northbridge fan

    First, my system specs:
    Intel Pentium 4 Prescott 2.8GHz HTT w/ 800MHz FSB
    Thermaltake Spark 7+ Xaser Edition A1715 CPU Cooler
    MSI 865PE Neo2-PFISR motherboard (BIOS ver. 3.8)
    2x512MB Kingston PC3200 DDR SDRAM @ 400MHz
    Maxtor 6Y120M0 120GB HDD 7200RPM SATA150 8MB cache
    Built-by-ATI Radeon 9800 Pro @ XT 128MB DDR 256-bit @ 415/744 (Catalyst 4.12)

    Enermax Noisetaker EG475P 470W PSU(+3.3V = 34A, +5V = 40A, +12V = 33A)
    Windows XP Pro SP2
    Even though on MSI's website the picture for the PFISR doesn't have a northbridge fan, mine does.  So, is there a reason why this thing is so bloody loud?  It sounds like a piece of plastic is just barely sticking up into the fans, creating a rattling sound.  If I turn my CPU fan speed down to a moderate speed, the NB fan is the loudest thing in my case, and I have five 80mm case fans and two PSU fans going full speed.
    Does my motherboard have fan control for this fan?  Is it possible to turn the speed down some?  What if it I just remove the damned thing altogether?  I don't really see the point of having the fan there anyway, since both it and the heatsink are so small that they can't really be moving that much heat.  How hot does the northbridge usually get?  Is it possible to overclock the northbridge and see any performance gain?

A shortcut will be created in that folder, right-click on the shortcut and choose cut, navigate to the startup folder, usually C:\Documents and Settings\All Users\Start Menu\Programs\Startup, and paste the shortcut into that folder. If you have a shortcut already on the desktop you could right click on that, choose copy and paste that shortcut into the startup folder. Speedfan will now startup with windows.
    Thanks, that worked perfectly.
    And I configured Speedfan to only run the NB fan at 75%, and it is now much quieter.  

  • Question about the fans

    Hi,
    I've just bought a new i5 15" Macbook pro that so far has been a dream.
    However, importing my photos yesterday to iphoto I noticed that the cpu temp climbed from 35 to 95 degrees very fast, in less than a minute in fact. This was not unexpected as the photo import was using over 80% of the CPU. However, the fans did not budge from 2000rpm. The temp was still climbing and I panicked and stopped the import.
    I then downloaded smc and cranked the fan speed up and the temp kept at around 65 degrees.
    What I am wondering is if I have a problem with the regulation of my fans, or if the temps climbed so fast that they didn't really have time to cut in. I'd have thought they'd have gone above 2000rpm at 95% CPU temp. Anyone else notice this with their fans?
    many thanks.

    Welcome to Apple Discussions
    Strange, it almost sounds like the temperature sensors were inactive or not reading correctly but if that was the case then the fan(s) should have been running at maximum revs (6000) as this is the default/failsafe mode ...
    You could try running the Hardware tests from your original install DVD (hold d at Boot) and see if it reports any SNS (temperature sensor) errors ?

  • Question about the fans spinning in the MSI GTX 980 gaming

    Hi everyone. I'm new to the forums and also new to MSI. I just bought one of their 980 gtx gaming cards.
    So far it seems pretty awesome. Was a little shocked when I realized that the fans on it don't even start spinning unless the card reaches at least 60 degrees. That's a really neat feature.
    However, I opened the side of the case and played some games for a bit to give it a test, and I noticed that even when the fans did start, they didn't both always start. At first it was just the right one, but then the left started as well after a while.
    Then a bit later, I noticed the right one was off and the left one was stopping.
    Is it normal for these MSI cards to be independent of each other?
    thanks.

    Frankly I didn't even bother finding out my stable clocks on stock voltage this time around and went directly to +87mV. I have a case with so-so airflow, and yet OC'ed, max load I never see temps above 72C (with 100% fan profile at 65C which is the max temp before Maxwells throttle).

  • Fan RPM's read 0 in BIOS no matter where I plug the CPU fan, but it registers in Core Center???

    Hey,
    I used to have BIOS Rev 1.0, updated to 1.2 thinking it would fix the problem about the Fan RPM's not registering, meaning they show 0 in the BIOS, but it didn't fix it, but it registers normally in Core Center in Windows XP Pro.
    What the heck is the problem?? are any other poeple getting this problem?, everything is correctly connected and operates correctly.
    Specs are in my signature.
    Thank you,
    Frank

    I have the same problem.  Don't worry too much about it.  Most BIOS' won't recognize a CPU fan below a certain threshold, and the Thermaltake Silent Boost's stock fan probably fits into that category.

  • Question about fan control MSI MPower

    Hi, Cosimo from Italy, sorry for my bad english.
    I have a question about fan control with the MSI MPower.
    The MPower site says: All 4-pin PWM fan connector Onboard
    But the manual says: SYSFAN1-4 pin 4 No Use
    My question is: the Control Center Fan Utility support the fan connect SYSFAN1-4 3 Pin voltage controled or 4 Pin pulse width controled or both?
    Thanks Cosimo.

  • Questions about macbook pro's fan speed

    i'm using a macbook pro early 2008
    and i use istatpro to monitor cpu gpu temp
    1. do the fans work with a min rpm around 2000 all the time?
    2. when i open quite a few apps, mbp get hot, and the gpu temp rises up to 80c degree also cpu temp rises to 60or70c degree. but the fan rpm is still around 2800.
    some guys using macbook/pro confirm that with temp around 80c, their fan has a rpm around 3000or4000.
    does someone else here have this situation above.
    is it normal?
    thanks a lot

    Welcome!
    1) Yes, the default fan speed is 2000 rpm. At that speed they are nearly silent. The speed will increase with temperature. Max revs possible are 6000 rpm.
    2) Notebook computers get hot, regardless of make. The temps you see are reasonable for graphic-intensive applications. The MBP will automatically shut down if the temps get too high; I believe the cutoff point is just over 100°C.
    There are third-party programs that allow you to customize fan settings but they must be used with care. It's possible to overwork the fans by manually setting their speeds too high.
    The best approach is to insure that the MBP gets to use all its built-in cooling capacity. Using the computer on a pillow or blanket is bad; the case bottom dissipates heat but only if air can get under it. Use a lapboard if you must use the computer in your lap.
    Exhaust air emits from the hinge area in the back of the case. make sure nothing blocks the case there or you'll get overheating.

  • The fan RPM increases a lot whenever i plug in my battery

  • Question About Photo Printers

    Excuse me for asking a question about photo printers here, but I could not find a place in the Apple Discussions form for printers.
    I'm thinking about buying an Epson R1900 printer since my primary selection criteria is the quality of glossy photographs.
    However, I have been told that use of the R1900 for general purposes (with a "standard" printer setting and non-photo paper) will detract from the R1900's performance when it will be used for printing photos (with photo RPM printer settings on premium photo paper or other media). But I just do not know whether this is correct. I was planning to have only one printer and expecting to use the photo printer as my "general purpose" printer (text, documents etc.).
    I would appreciate receiving advice/guidance from people who know about printers and/or people having with experience with the Epson R1900.
    Thanks for your help.

    I use my photo printer in two ways.
    For high quality prints I use the manufacturers Glossy paper and their expensive archival Quality inks for excellent results. More commonly though, I change out those ink cartridges and replace them with a cheaper water soluble ink bought online and use normal A4 copy paper for printing web pages and PDF documents.
    This second practice is about 60% cheaper in ink and copy paper is only about 1 cent per sheet and is satisfactory for such documents.
    The disadvantage is that is does require physically replacing one set of ink cartridges for the other, also if moving from basic to quality, I also do the inkhead alignment tests and adjustments to ensure that the output for glossy photos is going to be first rate.
    I find this necessary to prevent waste of good pigments, yet it still allows the printer to be used for more mundane usage of printing documents. The cost of printers is heavily discounted, as the manufacturers recoup their cost from the sale of ink. Hence one needs to have this dual usage in place to get the best of both worlds.
    This advice is not specific to one model photo printer, rather it is a general approach developed after spending too much money on good ink, printing web pages.
