Help Finding a HSF that will fit!

post #1 of 41
Thread Starter 
Hi, i currently have a Phenom 2 555 unlocked to the B55 and all cores are prime stable at stock speeds.
I have overclocked it to 4200 on stock hsf to see if it can boot and did it. Obviously i didnt prime it due to stock hsf.
i was idle around 41c but it has proven that i stands a good chance with a good HSF to overclock to good levels.
i just got a new case the Inwin Track. Beautiful case and great cable management. but due to its size i dont know
what size fan will fit and cool my CPU down enough to overclock to 4.2gz and prime stable.

Also i am wondering is it better to have a bigger HSF and no side fan, or a smaller HSF and a side fan. Due to my 22cm side fan or 2x12cm

Bigger heatsink with no side fan. And 4.2 is way, way too high for that processor.

Oh and you should measure the distance from the CPU to the sidepanel so we can give you better suggestions for an actual cooler. I can't find the data on InWin's website. You may want to look at coolers like the Noctua C14 though...

Thanks for the reply. I have put a tape measure down the side of my hsf for a rough guess and it says that it is about 18cm, also I have a mesh section that sticks out the side panel about a cm but I dont no if the hsf will line up with it.

also why is 4.2 bad for my cpu if I can find away of cooling it well enough to prime it?

it's just very very unlikely that it will be primestable at these clocks with an unlocked duocore Phenom 2...

For 30$ the 212 Evo or the Thermalright True Spirit 120 would be a good choice

For 40$ you can get a Thermalright HR-02 Macho, awesome performance AND very quiet

If you want something high end then get a Silver Arrow or a D14

I think that I would like to get it to 4ghz 26% increase is still good and im trying to keep good temps. I think the hr-02 seems a good one to go with but im still wondering if it will fit in my case as it is a midi case and I would prefer to keep my side fan as my MB temp is never above 28c so it keeps my case cool

cheers

Its not just about temperatures, that chip will just likely never be stable at that speed.

Even a 4 core Phenom II needs a lot of voltage / to be a really good chip to reach 4.2Ghz, and that unlocked 2 core is no doubt not as 'good' as a true 4 core, as there will be some defect in a core that made it be sold as a 2 core in the first place. No matter how much voltage you throw at it or how much heat you keep under control, it'll probably never be stable at 4.2.

Even 4Ghz prime stable may be shooting too high. Something in the 3.8 range maybe. Don't forget, chips will boot and run windows way, way before they can complete even 1 minute of Prime95, or any gaming / intensive taks for that matter.

Be careful though, Phenom's do produce a lot of heat, and you don't want to go over the 60 degree mark. Trying for a top overclock on a Phenom without one of the top air coolers like the Silver Arrow can be tricky, if your chip needs 1.5+ volts, as the chips just get too hot.

Thanks for the reply. I am very new to overclocking as this is the first pc I have built. I have had it to 3.7 on stock hsf and played assasin's creed just to see if it increases my fps with temps of 60c peak but my room temp was quite cold.

At stock speeds my computer boots in about 15 secs and is fast enough for me I was just wanting to see how hard I can push it with a ok hsf for about £30 to £50 that will fit in my case.

My guess is that you have max 160mm space for a heatsink. Inwin Track is 200mm wide and the bitfenix shinobi is 205mm but it has like 162mm of clearance for cpu hs (someone had a pic of HR02 in shinobi). Of course it depends on how much room you have behind the mobo tray (shinobi has loads), but I honestly don't think you can fit any (decent) tower heatsink with the 220mm fan on the doorpanel. I could easily be wrong as this is the first time I've heard of the case so this is just an estimate based on the width of the case.
If you want to have the big fan on the side panel, and I'm sure it cools the mobo and gpu down nicely, you can get a shallow heatsink like the Noctua C12 or Alpenföhn Gotthard.

Would the c12 cool my cpu enough to try and get 4ghz out of my b55 or because of the size of case would I have to look at water cooling ie h40 h60?

Behind my mobo plate is enough room for about 5mm till the side of the case due to cable management being next to the odd and it slants towards the side of the case .

thanks for the reply

Stop trying to get 4Ghz, that isn't how it works. You overclock little by little until you find your max, which is either restrained by stability or heat. In your case, heat is going to be a more likely restraint, even with the unlocked chip (which generally = less stable at higher clocks with 4 cores).

Start from stock, and increase little by little. That 3.7 you played AC with may not be stable - there is stable for 1 night and stable for a year. The two are different. You don't want to run a computer that isn't stable. It will soon just cause you problems like data corruption, constant crashes, and possibly hardware damage.

You're going at overclocking in far too of a rushed manner. You need to learn more and take your time. I've warned you, now don't learn what I mean the hard way.
