ThrottleStop: Monitor Disable CPU Throttling On Windows Laptops
Sofia Gilcrease
The download has been tested by an editor here on a PC and a list of features has been compiled; see below. We've also created some screenshots of ThrottleStop to illustrate the user interface and show the overall usage and features of this CPU benchmarking program.
ThrottleStop is a small application designed to monitor for and correct the 3 main types of CPU throttling that are being used on many laptop computers.The left side of ThrottleStop contains a variety of options which can be used to bypass CPU throttling and on the right side is a Monitoring panel that shows you the current state of each thread on your CPU.Some laptops are using clock modulation and multiplier reductions to lower the performance and power consumption of your computer. This is done deliberately to either allow your computer to run cooler or to allow your laptop to operate with a power adapter that is not sufficient to fully power your laptop and recharge its battery at the same time.When using ThrottleStop, it is strongly recommended to monitor power consumption at the wall with a Kill-a-Watt meter or similar device and make sure that you don't exceed the power capabilities of your power adapter. Use of ThrottleStop to bypass these throttling schemes is at your own risk and can result in permanent damage to your power adapter or computer or both which may not be covered by your warranty.
Hello, I've just built my new PC with a ryzen 9 5900x and I've done a stress test with Cinebench R23 on multicore while I had game boost enabled. The CPU temperature was already over 95 degrees celsius but there was no sign of stopping and it kept on rising while the thermal throttling didn't happen. I think I should reapply my thermal paste but I am more worried about why the throttling didn't start. Any ideas as to why that didn't happen?
Experienced gamers and gaming machine builders suggest that when you use the MSI game boost way too often, your PC can start to overheat, causing it to function at even a lower level of efficiency. We noticed something when we enabled the MSI game boost on one of our machines. Our Core I5-6600K Vcore was instantly set to 1.4v. So it clearly got too much voltage into the CPU Vcore and that is enough to damage the PC. As a rule of thumb, try to do any kind of OC manually, not automatically using a tool like MSI Gaming Boost and other similar ones.
Until MSI recodes Game Boost not to cause the CPU to go past its safety parameters it is best to not use this program. Plus the fact if it should damage your processor your 3 year AMD Warranty is voided since it was overclocked.
According to what I have read in HWINFO64 - HTC means Hardware Thermal Control and if it says "Yes" it indicates your processor is overheating. Since it is saying "No" when the Temp is over 90c it should say "yes"
I would use OCCT CPU to test your processor. There you will be able to see if the processor is throttling or not by its speed. If you see the temp go above 90c, your processor speed should start to slow down quite a bit to keep the processor from overheating.
Hi,
Try other bench tools like elstaci said, OCCT sure is very good for this.
Go to BIOS and check if there is nothing there overriding the thermal protection, like a manual profile or something.
in case of doubt, reset BIOS to defaults.
You haven't used third party softwares like throttlestop, right? Beware using these.
If you still can't find a reason, its time to check hardware level. If its OK, or maybe a fresh windows install.
Still not OK? You'd better start creating thermal limits in a profile inside Ryzen Master to stop it from going further and do some fan curve adjust so the system can start pumping some serious air when needed. Like 100% fans at 85C
Do you have the 4000D airflow or solid front? If you have the solid, check the side vents and test with the side panel open too.
Between these two cases, sometimes there's a 5-8C difference on the CPU if running on air. I know because I have the Obsidian 450D airflow and tested against the one with solid front. The intake fans wont send much air on the case with solid front.
And as always, check warranty status, you never know if something is really going bad.
Good Luck
I've seen a few differing reports around the net about when thermal throttling kicks in, with some saying 90 and others saying 100. So I'm not entirely sure what to believe, but if it's the latter then you haven't quite hit that ceiling.
Anyway, I'd imagine Game Boost is the culprit. It is the automatic overclocking util from MSi right? It's known to bump up voltages a lot (too much) at the same time as it bumps up speeds. Which in turn produces a ton of heat. I tried to find whether it disables thermal throttling but didn't find anything.
When I've installed my Noctua I've tightened the screws until the end so I doubt it might be because of not making good contact with the processor, more like the thermal paste not being spread evenly but this should still make the CPU thermal throttle.
Yes I have a Push-Pull CPU configuration, 3 pull in front, 1 exhaust in the back and 2 exhaust on top. On the CPU as well I have a push-pull with the 2 fans from Noctua faced towards the front case. I've checked the air flow and the fans are mounted okay, so there is no fan that should be mounted the other way.
Go into BIOS, search for Platform Thermal Limit - by default they should on Auto (or 0) to respect the value fused into the CPU. Set it manually to 90 (default for Ryzen 5000 series CPU's except for the 5600X), or lower if you want. The CPU should not operate much above the value you set.
I'm sorry to hear, but with that case and cooler, you should even touch 100C to begin with.
In normal working conditions, I mean, a well maintained computer and not OC'ed in anyway. I've not seen any 5800X/5900X/5950X go above 90C in a sustained way during stress test. Of course there are people that go way past that values but there's a reason behind it. For instances, a mini ITX build, very closed case, high ambient room temps, heavy OC or a insufficient cooler.
When you re apply thermal paste do the following:
- Clean very well the old paste from both CPU and cooler
- Is the thermal paste more than 2 years old, it should not be very important unless its dry.
- Check the copper plate on the cooler if its in someway damaged or with imperfections.
- The same as the above for the CPU IHS.
- Spread evenly or try a cross pattern of the thermal paste, I've noticed that the first CCD is running hotter
- Tighten the screws in a cross pattern with some sensible force, not too much but not too loose.
- Even if you hadn't done anything in BIOS, do the reset anyway.
- Undervolt the CPU it will help a lot, your board should have undervolt option by offset, apply something like negative 0.1v
- Try checking temps with XMP/DOCP off, higher speeds on ram will make IMC run hotter
- Check for BIOS updates for that board, if there are anything related to your problem.
In the end consider that it could be a faulty CPU and you may have to RMA it, but I would try another CPU before if you got the chance or the same CPU in another system.
Good luck and keep us posted
I am already running the latest BIOS version that is not a beta from MSI for my motherboard

Nothing wrong with setting the thermal limit manually. It's the best way to keep CPU temps under a limit you're comfortable with. Set the limit and the CPU won't exceed it. Game boost is overriding that, apparently.
That's what I was saying! Game Boost is notorious for raising the voltages in a big way and temps go up accordingly. There are numerous reports of it killing people's CPUs (though you may want to take them with a grain of salt). When you combine those two factors I can't help but think maybe it's disabling the throttling at the same time (even though I couldn't find reports of this).
66 degrees on the CPU running a Cinebench benchmark seems perfectly fine to me. That would indicate that the case cooling, heatsink paste and CPU cooler are all working just fine. It's only when you're artificially forcing the CPU to generate more heat that it's a problem. So I don't think you can "fix" your cooling. The only issue would be "why isn't it throttling"?
That question may hinge on how long you saw those super high temps. Were they momentary? Looking at the screenshots of the graph (thanks for the extra info) it looks like a momentary spike. Did you immediately shut it down when temps got that high? In which case maybe it didn't get a chance to throttle? I know this is quite old, but this is a nice little examination of thermal throttling -throttling/index.html
For the OP, maybe a better way to test whether throttling is happening is to apply the same overlocks as Game Boost manually. ie: if it sets voltage at 1.4v then do that manually. That way you remove the possibility that Game Boost is turning off throttling but you should still generate the same temps. So if/when your CPU gets that hot it should throttle successfully. Just be cautious since you really don't want to cook your CPU.
This tech article give you a very good explanation of both CPU Throttling and Thermal Throttling. It mentions how by using HWMonitor or HWInFO you can tell if your processor is throttling or not. It has images showing you the difference using the mention monitoring software: -and-thermal-throttling/
It also mentions using Windows Resource Monitor which will also show you if your processor is throttling or not. It shows you images and explain how you can tell by looking at it while running Resource Monitor (Type this in Windows Search perfmon.exe /res)
