oh theres space for 1 maybe 2 120mm fans along the top, just not enough space for the h80 ones (as theres 2 and the radiator)

So I'll try that, fans are only cheap after all.. Thank you for your help!

Where do the fans plug into btw? I take it that varies between each motherboard?

Yeah.. try to add 2 Cooler Master 120mm SickleFlow fans on top there and make them push the air out of the case.

Your power supply usually comes with a 12v power adapter with 2 molex plugs. If your motherboard doesn't have case fan power on the board itself you can use those molex plugs to connect those 2 fans to it.

Like this:

12v molex power splitter

And fan power plugs (usually fans do come with those fan/molex adapters though)

http://www.newegg.com/Product/Product.aspx?Item=N82E16812311003&nm_mc=KNC-GoogleAdwords&cm_mmc=KNC-GoogleAdwords-_-pla-_-Internal+Power+Cables-_-N82E16812311003&gclid=COrPp9GporUCFa57QgodvjMAJw

So here's what I suggest you do.

Keep your H80 setup as it is..

Add the 2 120mm fans on top of your case (if you can only fit one put only 1) and look for the arrow on the fan itself to put it in so it blow air out of the case.

Connect it to your motheboard chasis/case fan power or to the molex adapter.

Close the case and try it out..

If you see a drop in temp that's great.. you can then optionally add another 120mm fan on the bottom.. like here:

oE98

This will make your H80 blow air in, your front fan will blow air in, your bottom fan will blow air in and you top 2 fans will blow hot air out..

This should make your air flow inside great.

Excellent, I've ordered the fans and I'll let you know how it goes. I appreciate your help!

This is what you are going for... as far as heat dissipation goes

Also..that fan on the bottom is good for you because it will also blow over the GPU which well make it cooler as well.

With this setup you should get much better cooling and with H80 (which is btw a very good water cooling kit) you could push your overclock even higher.

Hi Boz,

I put 1 fan on the top as you said, pulling air out. And ordered 2 of the fans you said and put one on the front of the case (replacing the stock one) and one on the bottom.

My temps appear to be around the same. I'm thinking of swapping out the stock h80 fans now, as not only are they quite loud but don't seem to be doing their job that well.

Are there any particular fans you'd recommend, or would the ones you said before be suitable for the radiator too?

Thanks

(btw would epu power saving mode have any effect on temperatures?)

Hm... then you might have a problem with actual H80.. The fans you added are not waste though as you indeed needed a good heat dissipation and airflow in the case. Though they should have shown at least a few degrees difference, especially on motherboard chipset components. It's weird.

I have 2 Sickle Flow 120 mm fans on my H100 for example.. they run at 1750 rpm and cool the CPU quite efficiently.. the stock ones should provide better cooling even but they are loud.

it is kind of strange that you are still getting high temps. I'm really out of ideas.. What I would do if I was in your place is just try another cooler and see how it affects the cooling.. I think that if you put a fan like Sickle Flow on your H80 your temps will most likely go up due to silent fans usually running with lower rpm than stock ones and push slightly less air.

That is unless there's something wrong with the fan itself on H80. I guess it's worth the try as it is the cheapest solution for you to try out.

First time doing any overclocking so i'm pretty much a novice when it comes to it, been meaning to get into it, learn about it but never did. Today i did it via the bios and first attempt i got my dual core 3ghz to 3.3ghz. Pc seemed to be faster, games loaded up abit more faster too. Temp for my cpu was still around the 37c mark, popped to 40c when playing a game. I tried to overclock to 3.67GHZ but that crashed my pc at start up. So 3.4GHZ is my limit.

My question is, 2 programs, but both give me different readings.

See from picture.

On cpu-z it says 3.398ghz (so nearly 3.4ghz) But AIDA64 says CPU Clock is 2.2GHZ unless i'm seeing something, even windows say 3.4ghz

Aida can shows true values if You have SpeedStep enabled, so Your CPU drop clock when idle, if You have WinRAR or 7-zip use test mode to see if Your CPU rise when under load. Latest CPU-z always shows highest clock speed.

About Your OC, did You have set manual vcore or it is on auto, if on aute then cpu didn't have enough vcore on start

Oh got you. I will test it on WinRar now. On this Speedstep thing, i will check now, if it's disabled should i enable it then. The Vcore is auto, should i too change that to say 1.3 max? 1.5 is i hear bad?

Look at the multiplier value Orange, in CpuZ you`ll notice that it`s at x9 whereas in Aida it`s at x6. Basically this :)

SpeedStep - Automatically lowers the multiplier from its max. (9x for the E6850) to 6x when the machine is idle. The result is less power consumption and heat production. It goes back up to 9x when you start to get a CPU load. This is a power savings option.

I personally don`t like going to close to the limit. For the performance gain i don`t think it`s worth it.

Good luck

Ahh many thanks, Riggers. So idle it goes down to lower speed so it can't heat up etc. When i start to do stuff on the pc it will go back to the overclocked speed. Well i'm not pushing it anymore. This was a test for me. I will go back to 3.3ghz for today.

    • Lethal fake phone chargers are still being sold on Amazon and eBay, UK watchdog warns

      By zikalify · Posted

      Lethal fake phone chargers are still being sold on Amazon and eBay, UK watchdog warns by Paul Hill Credit: Pexels The UK consumer rights organization, Which?, is claiming that “potentially lethal knock-off chargers” are still being sold on online marketplaces seven years after it exposed the danger of these chargers. In its latest investigation, it bought 15 USB phone chargers from several online marketplaces and found they were missing key information, meaning they cannot be legally sold in the UK. Which? bought the 15 chargers from seven online marketplaces. These were Amazon (including Amazon Haul), AliExpress, B&Q Marketplace, Debenhams Marketplace, and eBay. It said that the chargers were so badly made that anyone using them was at risk of electric shock. Over half the chargers also posed fire and explosion risks. Of the chargers purchased, one was a fake Apple USB-C 35W power adaptor charger. To confuse buyers, the box was branded with an Apple logo, but testing found it to be a fake. Further testing picked up arcing sounds after 10 seconds of use, where a current jumps between two parts of the electrical circuit, which can cause fires, explosions, or electric shock. The manufacturers of this particular charger also put modeling clay inside it to make it feel more weighty, robust, and genuine. Not all of the chargers were technically faulty; however, some were missing key packaging, markings, and documentation, meaning they can’t be sold in the UK legally. Which? said that it is now campaigning alongside a coalition of safety groups and businesses for new laws that make online marketplaces responsible for ensuring the safety of products that they choose to list on their websites. It also said the government needs to start using powers under the Product Regulation and Metrology Act, which was adopted last July, to impose safety requirements on online marketplaces via secondary legislation, but so far, there have been delays. No matter what country you are in, be sure to properly research what you are buying and only buy authentic chargers to prevent fires. You can read more about Which?’s research here.
    • Visual Studio finally gets long-awaited feature that developers will love

      By Usama Jawad96 · Posted

      Visual Studio finally gets long-awaited feature that developers will love by Usama Jawad Visual Studio Code is Microsoft's popular, lightweight, open-source code editor, it is actually Visual Studio that is the company's flagship integrated development environment (IDE). Although the IDE already offers a boatload of useful features for developers, Microsoft has finally introduced a long-requested capability that will be loved by many. While developers have already been able to create Git pull requests (PRs) directly within Visual Studio for the past couple of years, it had not been possible to review a PR without switching to the browser, until now. Microsoft revealed in December 2025 that it is working on UX that enables developers to do just that, and fast-forward to June 2026, and Visual Studio finally has native capabilities to open and inspect a PR, discuss feedback, and wrap up the review, all without switching to the browser. This integration works for both GitHub and Azure DevOps (including on-prem). Developers have access to multiple surfaces to open a PR, including Git Repository, Git Changes, and the Git menu in Visual Studio. Once you open a PR, all the important details will be immediately visible to you, from where you can navigate to various levels of granularity and branch states, depending on the reviews that you are engaged in. As you would expect, you also get a diff view that enables you to see code changes inline or side-by-side in a separate panel. You can also review commit-by-commit. Additionally, this UX fosters collaboration as you can leave comments, reply to threads, and resolve conversations easily. Naturally, you can also leverage Copilot to apply a code suggestion to fix a potential issue. When you are done, you have the ability to approve, complete, and merge the PR. This is a pretty major feature as it has been requested heavily for the past few years. You can try it out in Visual Studio 2026 version 18.7, made available here recently. Microsoft plans to enhance this experience further in future releases with comment filtering, a timeline of PR activity, and more.
