Now that Summers here…

Hot weather and overheating system temperatures, Luckily I bring some tips to keep your system running cool.

Now that summer is here, it brings some issues.. No not rain!. Heat.

Brief points on what can be done to solve heat related issues.

1. Space

Having a spacious computer case not only means you have plenty of room for your Ultra Deluxe long Video card you’re eyeing up.. But also allows you to weave your airflow around your components.

Remember having extra space around your PC will allow more air to flow inside. Don’t stack items on top of the case or to the side, and don’t have your PC out in the open summer sun and don’t box it in tiny areas.

2. Dust

Dust build-up is the worst thing to happen to any of the components inside your PC, and when Humidity is thrown into it as well, it become even worse to remove.

Investing in a decent hoover and using it on the vents/heat sinks is a quick way to take it out of accessible places. A routine strip down and brushing cards/boards with a stiff photography brush helps too (SLOWLY), but Not recommended if you are not technical or careful.

For a routine, quick dust off- run your hoover over vents and openings. Make sure systems are off before you try this as you could damage fans. Especially in Laptops.

3. Dust Filtration

If you did invest in a bigger branded case, its likely that most of your fan area are open-able and contain thin gauze filters to stop dust getting in. These are designed to catch and occasionally clog up, clean then and brush them down and replace. You can also make your own to cover vent holes, if you can find non static gauze (apparently laundry sheets?) or custom sized thin gauze material (polyester or PVC) to cover vents.

We are currently looking for a supplier who’ll sell rolls of a thin enough material to make these up to slip in between fans and over vents.

Summer air seems a bit more humid in the early months so disposable filter material is more likely to work than a permanent solution

4. Cables

Route your cables so they are either flat on case-surfaces or bunched tightly and allow air to pass unhindered. If Air flow hits a tangle of cables, It’ll likely be thrown everywhere in the case and push other air flows about. We often Zip-tie down cable bundles and route along bottom, top and alongside drives/motherboard. Not only does it look neater if viewed with a window, but safely tucks everything out of the way.

We also try to use Modular PSU’s for this effect, reducing the amount of cables/plugs will help ease air flow restrictions.

Another system modders trick is to use small cuts of plumbing pipe to zip tie stiff cables to.

5. Airflow summer cooling article

Recently Case design changed for the better, previously we had PSU’s at the top which sucked air in from the case and out the back (ironically with the CPU straight underneath them) and now have PSU’s at the bottom taking air from underneath the case (with higher case feet and extra holes cut).

The ideal way air works is to match In and Out, fast or via volume. Of cause Water cooling will solve some of these issues, It brings some new questions and theories into the equation (plus some Water Cooler users aren’t happy that my air cooling got lower than their Water Cooler set-up)

The main issue with air flow cooling, the first components are going to warm the air, driving the next components temperatures up. Summer is an ideal time to do this as you can feel where the heat is collecting easier.

6. Consider upgrading the cooling systems

Studying CPU cooler benchmarks shows for around £20-£30 you can half your CPU temperature at the source, especially if you are using the standard heat-sink what came with the CPU.

Water cooling is becoming cheaper, and accessible, but requires a bit more maintenance (we still don’t like the idea of water near our PC’s!)

Extra fans don’t cost much these days (unless you want some fancy lighted silent ones..) and the benefit of a stable airflow reduces system stress as temperature drops.


Some of these sound too technical? Had a go and felt out of depth? Not to worry!
