CPU Temps Not Changing

iNonEntity · Sep 22, 2014

Using RealTemp and HWMonitor to check temperatures.
When I have the fan at max speed, the temperatures on my CPU stay the same as when the fan is at it's lowest. Is that normal? It doesn't exceed 70°C but I'd just like to know why the fan seems to change nothing.

edit: After looking at everything- changing all of my fans to minimum/maximum doesn't affect any of my temps at idle or full load even for long periods of time

It would help to know your hardware:

Although I don't have any specs which would help, I am assuming that either the software you are using is not correct as it is very rare the the temps at idle is the same as load. If it is then it is not good. I can't really say much else until the specs are given.

Sorry

Are you reading core temp or socket temp. Can you take a screenshot in HWmonitor when idle and again at 100% load after like two or three minutes and post them here. Actually, HWinfo might be better so we can see the fan speeds and voltages. It might take a couple of screenshots in HWinfo to get all the sensors for each situation, idle and load.

Link to the pictures. Sorry, I don't know how to display the picture in a comment.
HWMonitor doesn't record my case fans but there's definitely an audible difference when I put them at highest or lowest

How do you figure the temperatures are the same? I see core temps of 37 35 35 37 at idle and at load they are 64 61 67 64.

iNonEntity · Sep 22, 2014

No, the temps are the same when my fans are at highest/lowest. I'm asking why fan speed doesn't affect the temperature.

The left side shows when the fans are at their lowest RPM, the right side shows when they are highest. Regardless of fan speed, the temperatures are unaffected at all.

Darkbreeze · Sep 22, 2014

At idle, there should BE not change in fan speed, therefore, there should be no change in temperature. Any temperature change should be between idle and load. It's possible you have the wrong reported fan connected to the cpu fan header or have the cpu fan connected to a case fan header. If there is a change in fan speed, and no change in temperature, especially at load (Ignore idle, readings are usually wrong anyhow at idle.) then either the RPM being reported at the CPU fan speed is actually another fan, or there is a failed sensor.

iNonEntity · Sep 22, 2014

I use manual fan speed controllers and the change is audible. Regardless of the specs from sensors I know the RPM is higher. And the sensors pick up differences in my CPUs temperature for sure as you can see. Am I missing something?
(I know it sounds like I'm being douchey but I'm not intending to. I just don't understand this)

Darkbreeze · Sep 22, 2014

Ok, then you must be at the rooms ambient temp. No system can be cooler than the ambient temperature of the room regardless if you had a 3000 RPM fan going full speed. If the minimum temperature that the system can be at has already been reached at 1200 RPM, cranking it up to 2400 RPM isn't going to drop it any lower. Are you sure of the direction?

Darkbreeze · Sep 22, 2014

Whatever is going on has to have something to do with your manual controllers. At max temp at load, the temp could not possibly be the same at an RPM 1200 units apart.

iNonEntity · Sep 22, 2014

I didn't consider ambient temperature. I'm presuming that's what it is since my room isn't very cold, like 25°C or so.
What could be the problem with manual controllers

Darkbreeze · Sep 22, 2014

I'm not sure on that. I don't use them so I'm unfamiliar with problems related to them. I've never had any issues with the BIOS controlling fans as long as there are PWM headers and PWM fans, or a motherboard with voltage control capability for all the fan headers. IF there are not enough compliant headers, as some three pin headers are straight voltage and cannot be controlled through the BIOS, then splitters for the ones that can be have always solved the problem. I've found that way I've always had fairly accurate control and readings for fan speed and temp. Since I don't know what motherboard you have, you didn't include it with the specs above, I can't really tell you what yours has.

iNonEntity · Sep 22, 2014

MSI Z87-G45 Gaming sorry it's in my signature

Darkbreeze · Sep 22, 2014

All the headers on your board are PWM it seems, so that should be no problem should you choose to at least try things that way to see if it affects your readings and control.

iNonEntity · Sep 22, 2014

Try what? BIOS fan control? I honestly don't know how to set that up haha

Darkbreeze · Sep 22, 2014

Ok, to start with, and I don't mean to knock your hardware, really, but you need to throw that Zalman cooler away, or give it to somebody else, and put a real cooler in there. Since I know what motherboard you have, what is the brand and model of your case so I can recommend a good 120 or 140mm cooler instead of that 92mm cooler that has been around for years and just doesn't perform as well as newer units do. Even the entry level and much recommended budget Hyper 212 EVO from Cooler Master pretty much kicks it in the bits, hard, as you can see at the link below.

At high speed the 212 EVO had a 12.8c rise over ambient and 47.1dba noise level at max fan speed with a 125w load while the Zalman had a 23c rise over ambient and 53.2dba noise at the same max settings and load. The Zalman was almost twice as hot and had a 6db louder fan which is about the difference between the sound of breathing and the sound of a very quiet room fan at low speed. Upgrading to a good tower cooler or even one of the better downdraft coolers would make a big difference in your temps and at about 29.00 currently, isn't a big investment.

EVO vs Zalman CNPS9500AM2:

http://www.frostytech.com/articleview.cfm?articleid=2655&page=4

As for how to connect everything, just plug your CPU fan into the CPU Fan1 header and your case fans into the system headers. Then go into the BIOS and in Hardware Monitor click on CPU 1. Set the minimum and maximum target temperatures. I'd recommend about 10c minimum and 65c maximum. Then set the minimum and maximum fan speed sliders. I'd recommend 25% minimum and 100% or as high as it will allow on the maximum. Do the same thing for the case fans. You can play with the settings just like you can with the fan controller you have. I hate those fan controllers, every one I've ever worked with has been cheap and had problems, which is why I've never used them on my own rigs.

iNonEntity · Sep 23, 2014

That's funny cuz the EVO is actually the one I was debating on, but I was recommended Zalman because they are more trusted in CPU fans and it was made of copper. Also I love LEDs and don't favor liquid cooling. I might upgrade my cooler later but right now I'm strapped for cash.
My case is the Cooler Master Storm Stryker (I'm a CM fanboy so I'm more than willing to put more of their parts in my rig haha)

Darkbreeze · Sep 23, 2014

Actually, more Cooler master coolers, both air and liquid, place closer if not at, the top of the cpu cooler charts, than just about any other brand except maybe Noctua, Phanteks, Corsair and Scythe. Zalman does make good units, some of their liquid coolers are very good as are some of their traditional coolers, but that particular model is older and worked better on legacy processors than it does on modern ones.

iNonEntity · Sep 23, 2014

Well do you have a recommendation for an LED CM fan? It sounds dumb, but I'm all about aesthetics with my stuff

Darkbreeze · Sep 23, 2014

Actually, you can put any fan you want on the plastic brackets that attach the fans to most tower coolers that are fastened by bracket. The ones that fasten by clip don't even need that so as long as it's the right sized fan for the heatsink (120, 140mm), has PWM control and enough static pressure/cubic feet per minute airflow, it will work. I'll give you links to a couple of good cooler and just led fan solutions. Do you have a preference on fan body or led color?

iNonEntity · Sep 23, 2014

Most of my other LEDs are blue and my mobo is red/black, those are the color schemes I've been sticking with

Darkbreeze · Sep 23, 2014

Here is a pretty decent fan you can mount on the 212 EVO in place of the stock cooler that will match your color scheme, has good airflow and is relatively quiet. It's not going to be as quiet as say, a Noctua or a Blacknoise Noiseblocker, but it's not terrible. And certainly more quiet than the stock fan on the EVO or your Zalman. It comes in blue, green or red so whatever you like.

Or this one that cools almost twice as well, but is also twice as loud at full speed:

Or, you could go with something like this, if money isn't a major concern:
